Unusual stereo- and chemo-selective photocyclization of chiral α-aminoacid-incorporated 2-acyl benzamides by control of chiral memory

Oxidative coupling of enolates using memory of chirality: an original enantioselective synthesis of quaternary α-amino acid derivatives

We describe here the first enantioselective oxidative heterocoupling of enolates. Our strategy relies on the memory of chirality concept and allows the stereocontrolled formation of quaternary centres on α-amino acid derivatives with an enantiomeric excess of up to 94%.
