N-Substituted 2-amino-4-pentenoic acid derivatives employed for the protection of racemic amino acids were shown to be capable of permitting the chromatographic separation of R and S isomers. When N(α) was disubstituted with benzyl and phenylfluorenyl groups, the racemic amino acids could be separated with facility on open silica gel columns. Further, the optically pure N-protected amino acids so derived could be used for the preparation of misacylated suppressor transfer RNAs. (C) 2000 Elsevier Science Ltd.
