Novel seven-membered iminosugars fused thiazolidin-4-one and benzthiazinan-4-one were conveniently synthesized by the tandem Staudinger/aza-Wittig/cyclization reaction under microwave radiation. Benzoyl group (Bz) migrations were found in the synthesis of 8c and 9b using D-galactoside or D-mannoside as starting materials, respectively, which was suggested by HMBC and X-ray. The new bi/tricyclic iminosugars
通过串联的Staudinger / aza-Wittig /环化反应在微波辐射下方便地合成了融合了噻唑烷丁-4-酮和苯并噻嗪南-4-酮的新型七元亚氨基糖。HMBC和X射线表明,分别以D-半乳糖苷或D-甘露糖苷为原料,在8c和9b的合成中发现了苯甲酰基(Bz)迁移。检查了新的双/三环亚氨基糖3〜4(ad)和5(bd)的HIV逆转录酶(RT)抑制活性。结果表明,除5b外的所有化合物均可有效抑制RT活性。其中,化合物3c和4c是最好的化合物,其RT抑制活性的IC50值分别为2.11 microM和2.73 microM。
