  Synthesis of polyhydroxylated indolizidine and quinolizidine compounds--potent inhibitors of α-glucosidase I

  摘要：

  Polyhydroxylated indolizidine 6a and quinolizidine 6b were synthesized from a common precursor, iminoheptitol 8. The target compounds are potent inhibitors of the glycoprotein trimming enzyme--alpha-glucosidase I.

• Access to Homoglyconojirimycins via Ring Isomerisation of Penta­hydroxylated Azepanes
  作者：Yves Blériot、Tao Liu、Yongmin Zhang

  DOI：10.1055/s-2007-973884

  日期：2007.4

  N-Benzyl pentahydroxyazepanes undergo ring isomerization during mesylation of the hydroxyl group β to the nitrogen via a neighboring nitrogen participation involving a transient aziridinium species which is trapped by chlorine. The resulting chloro­methyl tetrahydroxypiperidines have been converted into the corresponding homoglyconojirimycins.

  N-苄基五羟基氮杂环庚烷在对氮原子的β羟基进行梅斯化时，会经历环异构化，涉及一个邻近氮原子的参与，形成一个短暂的氮杂环烷类中间体，该中间体被氯捕获。最终得到的氯甲基四羟基哌啶已被转化为相应的同糖酸酶抑制剂。

  The present invention describes a group of polyhydroxylated indolizidines and quinolizidines and their esters. These compounds are prepared starting from 2,6-dideoxy-2,6-dideoxy-2,6-imino-1,3,4,5-tetrakis-O- (phenylmethyl)-D-glycero-L-gulo-heptitol or a corresponding N-substituted compound. The compounds are useful in the treatment of diabetes and as .alpha.-glucosidase I inhibitors.
