Synthesis of 2-C-(4-aminocarbonyl-2-thiazoyl)-1,4-anhydro-l-xylitols and their fluoro derivatives
摘要:
3,5-O-Benzylidene-2-C-cyano-1,4-anhydro-L-xylitol 7 was synthesized stereoselectively from D-xylose in 7 steps. 2-C-(4-Aminocarbonyl-2-thiazoyl)-1,4-anhydro-L-xylitols and their fluoro derivatives were synthesized from the cyanohydrin 7. Fluorination of compound 9 proceeded with retention of configuration using diethylaminosulfur trifluoride (DAST). (C) 1998 Elsevier Science Ltd. All rights reserved.
