Novel C—C Bond Formation Through Addition of Ammonium Ylides to ArylalA Facile Approach to β-Aryl-β-hydroxy α-Amino Acid Frameworks.
14- 096 dehydes:
— Ammonium ylides, generated in situ from α-diazo esters (I) and amines (II), in the
presence of a Rh-catalyst undergo an aldol-type reaction with aldehydes (III) affording
highly substituted amino acid frameworks (V) in a convergent, three-component reaction. In all cases title compounds (V) are obtained in competition with the N-H insertion
products (IV). — (WANG, Y.; CHEN, Z.; MI, A.; HU*, W.; Chem. Commun.
