A few bicyclic hybrid sugar molecules comprising of oxa-aza, oxa-oxa, and oxa-carbasugar fused skeletons were designed and synthesized from C-2 acetoxyglucal involving Ferrier rearrangement, Grignard addition, and ring-closing metathesis as key steps. The inhibitory activities of the synthesized molecules were tested against commercially available enzymes, which revealed the sugar–piperidine and sugar–pyran
由C-2乙酰氧基葡萄糖设计并合成了一些由oxa-aza,oxa-oxa和oxa-carbasugar融合的骨架组成的双环杂化糖分子,这些步骤涉及Ferrier重排,Grignard加成和闭环易位。测试了合成分子对市售酶的抑制活性,这揭示了糖-哌啶和糖-吡喃杂种是有效的和选择性的抑制剂。
