Too much fiber? Protein fibers play an
important role in cellular processes, but
are also involved in protein-folding diseases, such as Alzheimer?s disease.
Modern screening and validation models
allow the investigation of the aggregation
and deaggregation kinetics of protein
fibers (see scheme). These studies can
serve as a starting point for the development of new therapeutic strategies.
Taming of the flu: Shikimic and quinic
acids are the established starting materials for Tamiflu, a viral neuraminidase
inhibitor that is considered by many as the
first-line treatment against a possible
H5N1 (bird flu) pandemic. Several synth-
eses have been described recently that
circumvent the use of these natural
products. These, or related approaches,
may provide an alternative practical
approach to this important drug.

Reactions that go with the flow: Many
applications in chemical research require
multiple reactions to be performed in
parallel and in series. Microfluidic droplets can be used as chemical microreactors for performing many reactions on
small scale (see picture). New techniques
in droplet-based microfluidics and their
applications (e.g., for analysis of complex
biological processes or optimization of
reaction conditions) are discussed.

Hydrogen Storage
First-class accommodation: A series of
coordination frameworks with different
pore sizes (see structure of one; Cu blue,
C gray, H white, O red) are prepared from
CuII ions and carboxylate ligands of various lengths. Comparison of their sorption properties reveals that smaller pores
allow higher densities of adsorbed H2,
whereas larger pores allow higher maximum H2 storage capacities.

A sunny outlook: As the first fully heterocyclic circulene, sulflower opens the way
to an unprecedented class of compounds
that are both organic and inorganic. Sulflower is an oligothiophene as well as a
new form of carbon sulfide that resembles
a flower (see picture) and was synthesized
in a short and effective approach.

A new approach to stabilization of ZnO
nanocrystals by ionic-liquid components,
which endow the nanocrystals with high
thermal stability and good fluidity, is
demonstrated. The ionic-liquid/ZnO
composites exhibit tunable photoluminescence (see picture) with a high quantum yield.
ZnO Nanocrystals
Unbalanced surface stresses, induced in
stereocomplex crystals formed by blends
of two enantiomeric polylactide diblock
copolymers by the presence of immiscible
blocks of different lengths, result in
lamella curving and formation of onionlike multilamellar structures (see picture
for schematic structure and a TEM

Reversible Size Modification of Iron and

Wheelin? and dealin?: The M10 molecular
wheels [M10(OMe)20(O2CR)10] (M = Ga,
R = Me; M = Fe, R = Ph) were modified to
M18 wheels in a nontemplate synthesis
upon incorporation of a diolate ligand
(see space-filling model of [Ga18(pd)12(pdH)12(O2CMe)6(NO3)6]6+; Ga yellow,
O red, N blue, C gray; pdH2 = 1,3-propanediol). Remarkably, dissolution in MeOH
converts both M18 wheels back into the
M10 wheels.
DNA Structures
Highly sensitive: Analysis of viral DNA
(M13 phage) is possible by using a DNAbased machine that is fueled by dNTPs
and synthesizes DNAzyme reporter units.
The DNAzymes mimic peroxidase and
lead to a colorimetric or chemiluminescent readout of the analyzed DNA.

Bound to have similarities: Although the
overall shape of discodermolide bound to
tubulin resembles the structure of the free
ligand, the precise conformation and
orientation of the lactone ring are different. A partially overlapping pharmacophore model supported by protein-mediated interligand NOE signals (see picture)
is proposed to explain the similar (but not
fully equivalent) biological activity of discodermolide and epothilone A.
High-valent versatility: N4Py is a versatile
pentadentate ligand demonstrated to
stabilize both high-valent oxo and imido
compounds. The [FeIV(NTs)(N4Py)]2+
complex (see DFT-optimized structure)
has been characterized spectroscopically
and formulated as having an S = 1
iron(IV) center with an Fe=N bond
(1.73 R) that is longer than the Fe=O bond
of its oxo analogue (1.65 R).

Cycloaddition of o-benzoquinone imides
with chiral ketene enolates derived from
cinchona alkaloid catalysts is the basis of
a catalytic asymmetric synthesis of 1,4benzoxazinones and 1,4-benzoxazines.
The resulting cycloadducts can be deriva-
tized in situ to provide a-amino acid
products in good-to-excellent yields with
very high enantioselectivities (see
scheme; CAN = ceric ammonium nitrate,
Nu = nucleophile).
Catalytic, Asymmetric Synthesis of
1,4-Benzoxazinones: A Remarkably
Enantioselective Route to a-Amino Acid
Derivatives from o-Benzoquinone Imides
Giving it a tri: Ternary complexes formed
from a macrocyclic host (p-sulfonatocalix[4]arene), an organic guest (2,3diazabicyclo[2.2.2]oct-2-ene), and transition-metal ions (see picture) result in a
host-assisted formation of a metal?ligand
bond. The system displays a very high
selectivity as a result of triple supramolecular recognition involving Coulombic interactions, hydrophobic guest binding, and weak metal?ligand interactions.
Supramolecular Chemistry
Surface value: Scanning tunneling microscopy reveals that aryl?carbonyl assemblies
form through C HиииO interactions on a
Pt(111) surface (see picture). The strong
hydrogen bonding is activated by the
chemisorption-induced polarization of the
arene and is tunable by substitution on
the aromatic ring. These findings are
relevant to stereoselective heterogeneous
and homogeneous catalysis.

Behind bars: A single molecule of the
protein cytochrome c has been incarcerated within a rigid tetrahedral DNA cage
(see picture). The central cavity is estimated to be large enough to accommodate a sphere of approximately 2.6 nm in
radius, such as a 60-kDa globular protein
(Mr of cytochrome c: 12.4 kDa). The finding demonstrates the potential of DNA
containers as a new kind of drug-delivery

Three-Step Synthesis of Sialic Acids and
Derivatives
Flexible yet efficient: Sialic acids such as
l-N-acetylneuraminic acid (see picture)
can be synthesized in only three steps by
1) vinylation of an aldose through a
modified Petasis coupling reaction, 2) 1,3-
dipolar cycloaddition with a nitrone to
construct an isoxazolidine ring, and
3) base-catalyzed b elimination/ring
opening of the isoxazolidine to generate a
g-hydroxy-a-keto acid.
A C1 source, the carbido complex [Ru(C)(PCy3)2Cl2] (1) adds cleanly to dimethylacetylene dicarboxylate (DMAD), affording the cyclopropenylidene complex 2
(red O, green Cl, yellow P, gray C). This
product is surprising given the instability
of its trans-cyclopropylidene analogue. HX
reagents effect 1,1-addition and ring
opening, forming vinylidene complexes
such as 3 which catalyze the ring-opening
metathesis polymerization of norbornene.

A golden tandem reaction: The
[PPh3AuCl]/AgSbF6 catalytic system promotes a tandem reaction composed of a
Friedel?Crafts-type addition of electronrich aromatic and heteroaromatic derivatives to unactivated alkenes and a carbocyclization (see scheme; Z = C(CO2Me)2,
C(SO2Ph)2, O, NTs). The reaction is
compatible with various functional groups
on the enynes and nucleophiles, and
proceeds rapidly at room temperature.
Going retro: Controlled-potential electrolysis (CPE) is employed as a synthetic tool
in the selective removal of addends from
fullerene adducts. Reductive CPE has
been extensively used in the retro-cyclopropanation of fullerenes without affecting pyrrolidine addends also present. Now
oxidative CPE for the selective removal of
pyrrolidine addends in the presence of
methano adducts is reported (see
scheme).

Cast in a new role: Aqueous solutions of
OsO4 and NaIO4 oxidize methane to
methanol under very mild conditions (see
scheme). The generated methanol is preserved over 5 days at 50 8C, although it is
more readily oxidized than methane in
separate experiments. Remarkably,
methanol oxidation by aqueous OsO4/
NaIO4 is inhibited by the presence of
methane.

Brushing up on films: A simple model,
based on strong ion-pairing interactions
of a dye probe (bromothymol blue, BTB)
within surface-grafted charged polyelectrolyte brushes, provides evidence that
physical forces can be easily mechano-
transducted into chemical signals (see
picture, PDMS = poly(dimethylsiloxane)).
The application of a mechanical force
results in a shift of the equilibrium for
BTB, which can be monitored by UV/Vis
spectroscopy.

About the size of it: A series of polystyrene-block-poly(acrylic acid) (PS-b-PAA)
block copolymers were developed in
which the length of the PAA block was

block was varied. This allowed a study of
the effect of the PAA/PS block ratio on the

A negative disposition: Electronic-bandstructure calculations reveal that in
La2M2In (M = Pt, Cu) the transition-metal
atoms can be regarded as anions with
fully occupied nd orbitals and bonding
characters similar to that of the Ge3 ions
in La2Ge2In. The orbital sequence in
La2M2In is (n + 1)s < nd < (n + 1)p, as a
result of the low oxidation states of the
