Abstract

Abstract Bromoallenes 3a and 3b derived from (D)-Serine undergo SN 2′ alkylation with organo copper reagents to give alkynyl amino alcohol derivatives. These compounds can be further transformed into branched enantiometrically enriched α-amino acids as, for example (L)-Isolcucine and (L)-Alloisoleucine.
