Novel C–C bond formation through addition of ammonium ylides to arylaldehydes: a facile approach to β-aryl-β-hydroxy α-amino acid frameworks†
Abstract
Ammonium ylides generated in situ from α-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.
