摘要:
We report herein an unprecedented concept for an enantiospecific synthetic strategy for alpha-amino acid derivatives starting from Ugi four-component coupling reaction employing chiral amine, via a chiral morpholinone intermediate. This concept was proven by the successful synthesis of (S)-N-Ac-tert-leucine.
