ABSTRACT:
A review. Several tools necessary for the synthesis of peptides from .alpha.-amino acids are considered here. Different strategies for the asym. synthesis of .alpha.-amino acids are described. New chiral glycine and alanine imines as acyclic and cyclic templates for the asym. synthesis of different types of mono as well as dialkylated .alpha.-amino acids with acyclic and heterocyclic structures are reviewed. New polymer-supported cinchonidine and cinchonine ammonium salts and chiral binaphthol-derived aminoalkoxides (BINOLAMs), have been developed as catalysts for the asym. PTC alkylation of imino esters. For the protection of .alpha.-amino acids new efficient reagents, Fmoc-P-OSu and Cbz-P-OSu [P-HOSu; poly(styrene-co-N-hydroxymaleimide)], have been developed.
