  吡喃部分稠合的吡喃酮环的构建和功能化：新型的吡喃并[4,3 - b ]吡喃-5（4 H）-酮作为sirtuins的潜在抑制剂的设计与合成

  摘要：

  基于新型吡喃并[4,3 - b ]吡喃-5（4 H）-one的小分子被设计为sirtuins的潜在抑制剂（即酵母sir2，人SIRT1的同系物）。这些化合物的精细合成是通过一个多步骤序列进行的，该步骤包括MCR，Sandmeyer型碘化，Sonogashira型偶联，然后进行碘环化，然后进行Pd介导的各种C–C键形成反应。总体策略涉及吡喃环的构建，然后是稠合的吡喃酮部分，以及随后在所得核吡喃并[4,3 - b ]吡喃-5（4 H）-one骨架的C-8位置上进行的功能化。代表性的碘化内酯化产物的晶体结构分析（6d） 被表达。在体外针对酵母sir2进行测试时，某些合成的化合物显示出有希望的抑制活性。化合物6g 对酵母sir2表现出剂量依赖性抑制作用（IC 50 = 78.05μM），并且与该蛋白质在计算机上具有良好的相互作用。

  摘要：

  Twenty‐one novel 2‐aryloxy‐3‐(4‐chlorophenyl)‐8‐substituted‐5‐aryl‐8,9‐dihydro‐3H‐chromeno[2,3‐d]pyrimidine‐4,6(5H,7H)‐diones 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h, 5i, 5j, 5k, 5l, 5m, 5n, 5o, 5p, 5q, 5r, 5s, 5t, 5u were designed and easily synthesized via a tandem aza‐Wittig reaction. Treatment of iminophosphorane 3 with 4‐chlorophenyl iso‐cyanate gave carbodiimide 4, which reacted with phenols to provide the title compounds in 50–73% isolated yields. All compounds 3 and 5 were confirmed by infrared, 1H‐NMR, mass spectra, and elemental analysis, and compound 5a was further analyzed by single‐crystal X‐ray diffraction, and the title compounds were synthesized with the purpose of bringing in some new chemical and biological interests.
