Novel C-C bond formation through addition of ammonium ylides to arylaldehydes: a facile approach to beta-aryl-beta-hydroxy alpha-amino acid frameworks

Chem Commun (Camb). 2004 Nov 7:(21):2486-7. doi: 10.1039/b407449a. Epub 2004 Sep 14.

Abstract

Ammonium ylides generated in situ from [small alpha]-diazo esters and amines in the presence of catalytic Rh2(OAc)4, undergo an aldol-type reaction with aldehydes affording highly substituted amino acid frameworks in a convergent, three-component reaction.
