4R)-Bengamide E (2) was synthesized starting from d -glucono-δ-lactone (3) and the key deoxygenation step from 13 to 15 was achieved by the application of NaBH3CN and ZnI2. Compared with natural bengamide E (1), the synthetic compound (3S,4R)-bengamide E (2) was inactive against the cell growth of HUVEC and cancer cells. These data represent the significance of the stereochemistry at C-3 and C-4 of
摘要以d-葡萄糖酸-δ-内酯(3)为原料,合成了(3S,4R)-苯甲酰胺E(2),并应用NaBH3CN和ZnI2实现了从13到15的关键脱氧步骤。与天然苯甲酰胺E(1)相比,合成化合物(3S,4R)-苯甲酰胺E(2)对HUVEC和癌细胞的细胞生长无活性。这些数据代表苯甲酰胺在C-3和C-4的立体化学对于结构识别和与靶标结合的重要性。
