摘要

Excellent regiospecificity has been achieved in the reaction of carbon nucleophiles with N- para-toluenesulfonylaziridine-2-carboxylic acid (6, R= H protected as the anion. This has been developed into a general and high yielding synthesis of optically pure α-amino acids containing one chiral centre. When the aziridine (20) containing a second chiral centre was used, only lithium trimethylsilylacetylide gave the desired α-amino acid. Reaction with ...
