摘要:
Hetero Diels-Alder reaction between 2-aza-3-trimethylsilyloxy-1,3-diene and aldehydes gives rise to tetrahydrooxazin-4-ones, useful intermediates in the synthesis of alpha-amino-beta-hydroxy acids. Herein we report the complete stereoselective synthesis of D-serine Cbz-methyl ester. (C) 2002 Elsevier Science Ltd. All rights reserved.
