摘要
Crystalline 1,3,4,5-tetra-O-acetyl-6-bromo-6-deoxy-keto-D-fructose was prepared by reaction of 1, 3,4,5-tetra-O-acetyl-D-fructopyranose with triphenylphosphane dibromide in dichloromethane. Subsequent deprotection followed by reaction of the free 6-bromodeoxyfructofuranose with sodium azide in N,N-dimethylformamide furnished the corresponding 6-azidodeoxyketose. Catalytic hydrogenation led to 1-deoxymannojirimycin in 27% overall yield from 1, 3,4,5-tetra-O-acetyl-D-fructopyranose. This access is simple, inexpensive, high-yielding and clearly suitable for multigram preparations. (C) 2002 Elsevier Science Ltd. All rights reserved.
