The synthesis of new analogues of the naturally occurring glycosidase inhibitor, salacinol, and its ammonium analogue, ghavamiol is described. These analogues contain an additional hydroxymethyl group at C-1, which was intended to form additional polar contacts within the active site of glycosidase enzymes. The target zwitterionic compounds were synthesized by means of nucleophilic attack at the least
描述了天然存在的糖苷酶抑制剂新的类似物salacinol及其铵类似物ghavamiol的合成。这些类似物在C-1处包含一个额外的羟甲基,旨在在糖苷酶的活性位点内形成额外的极性接触。目标两性离子化合物是通过亲核攻击在2,4-O-亚苄基-1-(或d)-赤藓糖醇1,3-环硫酸盐的受阻最少的碳原子上由2,5-脱水-1,3合成的: 4,6-二-O-亚苄基-2,5-二脱氧-5-硫代(或1,5-亚氨基)-1-ID醇。
