  Potent glycosidase inhibitors via hetero Diels-Alder reactions: asymmetric synthesis of 5-methyl-trihydroxypyrrolidines

  摘要：

  Some straightforward chemical transformations of oxazine diol 4, which was obtained from sorbaldehyde 2 by an asymmetric hetero Diels-Alder reaction followed by osmylation, led to the protected dihydroxypyrrolidine-aldehyde 8a and, after basic epimerisation, to 8b. Reduction of the aldehyde moiety and deprotection gave the potent glycosidase inhibitors 2,5,6-trideoxy-2,5-imino-D-altritol and D-allitol 9a and 9b. (C) 1997 Elsevier Science Ltd.

  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.
