Benzylidene Acetal Fragmentation Route to 6-Deoxy Sugars: Direct Reductive
in the Presence of Ether Protecting Groups, Permitting the Efficient,
44- 222 Cleavage
Highly Stereocontrolled Synthesis of β-D-Rhamnosides from D-Mannosyl Glycosyl Donors. Total Synthesis of α-D-Gal-(1→3)-α-D-Rha-(1→3)-β-D-Rha-(1→4)-β-D-Glu-OMe, the Repeating Unit of the Antigenic Lipopolysaccharide
from Escherichia hermannii ATCC 33650 and 33652. — The preparation of
β-D-rhamnosides is realized by deoxygenation of appropriately protected mannosides
which are available in high yields and with high stereoselectivity. The method is applied
to the synthesis of title compound (V). — (CRICH*, D.; YAO, Q.; J. Am. Chem. Soc.
