摘要:
Mono-O-acylation of (R)-2-(alpha-methylbenzyl)amino-1,3-propanediol 1 with 4-nitrobenzoyl chloride and DMAP in dichloromethane at room temperature gave crystals of optically active (2S,alphaR)-3-hydroxy-2-(alpha-methylbenzyl)aminopropyl 4-nitrobenzoate hydrochloride [(2S)-2a(.)HCl] in 33% yield by fractional crystallization. Optically active oxazolidinones, aziridines, and serinol derivatives were synthesized from the benzoate (2S)-2a. (C) 2003 Elsevier Ltd. All rights reserved.
