    Synthesis of Novel 2-Aryloxy-3-(4-chlorophenyl)-8-substituted-5-aryl-8,9-dihydro-3H-chromeno[2,3-d]pyrimidine-4,6(5H,7H)-dione Derivatives
    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.

    摘要:
    2-苯甲酰-1,3-茚酮和含氰基苯甲基马隆酰亚胺、乙基苯甲基氰乙酸酯、苯甲基氰乙酸酰胺和苯甲基氰乙酸苯胺在25°C下与n-丁硫醇在20%乙醇-80% pH 7缓冲液中的反应速率过快,无法通过标准方法测量。平衡常数已经计算,并与Hammett σ和Taft σ*常数相关联。这些和其他与n-丁硫醇在相同实验条件下以可测速率几乎完全反应的双官能团系统的反应差异被归因于苯基对顺式官能团在反向反应中的参与。结果表明,n-丁硫醇通过1,4-机理加成于肉桂酮苯乙酮,讨论了这种亲核试剂与具有扩展共轭体系的类似化合物的反应。
