  名称：

  Chiral 5-Methyl-trihydroxypyrrolidines—Preparation from 1,2-Oxazines and Glycosidase Inhibitory Properties

  摘要：

  Chemical transformations of chiral 1,2-oxazines 4, 5 gave the 2,5,6-trideoxy-2,5-imino D-alditols 12b, 13b in the D-altritol and D-talitol series, respectively. Basic aldehyde epimerisation led to the D-allitol isomer 15b. Compound 12b is a potent alpha-L-fucosidase and alpha-D-galactosidase inhibitor. (C) 2000 Elsevier Science Ltd. All rights reserved.
