Optically active sugar thioamides from δ-gluconolactone
摘要:
This paper describes a facile and rapid approach to N-alkyl- and N-aryl-thiogluconamides employing delta-gluconolactone as starting material. The protocol involves a three-step sequence to afford the corresponding thioamides as crystalline substances in moderate to good yields. The Lawesson reagent was found to be the reagent of choice to accomplish the key transformation amide-thioamide. (C) 2000 Elsevier Science Ltd. All rights reserved.
