A straightforward and efficient synthetic route to a new class of glycosidase inhibitors containing an oxazole-2(3H)-thione moiety has been devised. The approach involves the formation of α-hydroxy ketones, which, after condensation with thiocyanic acid, leads to the formation of the heterocycle. By exploiting the ability of the nitrogen atom of oxazoline-2thione precursors to act as nucleophiles in
已经设计了一种直接且有效的合成路线,用于合成含有 oxazole-2(3H)-thione 部分的新型糖苷酶抑制剂。该方法涉及α-羟基酮的形成,其与硫氰酸缩合后导致杂环的形成。通过利用恶唑啉-2硫酮前体的氮原子在分子内加成中充当亲核试剂的能力,栗精胺类似物可以很容易地以良好的总产率制备。糖苷酶抑制活性
