  Synthesis of polyhydroxy 7- and N-alkyl-azepanes as potent glycosidase inhibitors

  摘要：

  An effective synthetic method for polyhydroxylated azepanes that contain an alkyl group (Me or Bu) at either the 7- or N-positions is developed. The synthetic routes are accomplished in eight to ten steps from D-(-)-quinic acid. Among the compounds synthesized, the polyhydroxy 7-butyl azepane (compound 3), which possessed the R-configuration at C-7 position, is shown to give potent inhibition against beta-galactosidase (IC50 = 3 mu M). Preliminary biological data indicate that the length of alkyl groups along with the proper stereochemistry at the C-7 position is essential for acquiring extra binding affinity. Using similar synthetic routes, the polyhydroxy N-methyl and N-butyl azepanes are synthesized for the comparison of their biological activities. (C) 2010 Elsevier Ltd. All rights reserved.

  Several new stereoisomers of 3,4,6-trihydroxyazepanes and 7-hydroxymethyl-3,4,5-trihydroxyazepanes as well as known 3,4,5-trihydroxyazepanes were synthesized as potent glycosidase inhibitors from d-(−)-quinic acid in an efficient manner. The key step employs dihydroxylation of protected chiral 1,4,5-cyclohex-2-enetriols under RuCl3/NaIO4/phosphate buffer (pH 7) condition, followed by reductive amino cyclization

  由d -（-）-奎宁酸合成了3,4,6-三羟基氮杂环庚烷和7-羟甲基-3,4,5-三羟基氮杂环庚烷以及已知的3,4,5-三羟基氮杂环庚烷作为强大的糖苷酶抑制剂。一种有效的方式。关键步骤是在RuCl 3 / NaIO 4 /磷酸盐缓冲液（pH 7）条件下，将受保护的手性1,4,5-环己-2-烯三醇进行二羟基化，然后进行还原性氨基环化反应。我们发现选择合适的手性1,4,5-环己-2-烯三醇的C1-OH保护基会增加环化的收率。初步的生物学数据表明，其中某些氮杂环丙烷对α-甘露糖苷酶和α-岩藻糖苷酶具有有效的抑制作用。
