One-step synthesis of optically active benzyl N-trityl-L-aziridine-2-carboxylic esters
摘要:
Benzyl N-trityl-L-serine or threonine esters give upon treatment with sulphuryl chloride the corresponding benzyl (2S)-1-trityl-2-aziridine carboxylate or (2S, 3S)-1-trityl-3-methyl-2-aziridinecarboxylate esters in excellent yields.
