A strategy for the total synthesis of the highly potent glucose-6-phosphate translocase inhibitor mumbaistatin (1) and structural analogues was elaborated. Such compounds represent a lead structure in the development of potential new drugs for the treatment of diabetes. To evaluate the general strategy, the close mumbaistatin analogue 10 was synthesized in a convergent manner. The anthraquinone building
拟定了高效合成6-磷酸葡萄糖转运酶抑制剂孟买他汀(1)和结构类似物的全合成策略。这些化合物代表了潜在的治疗糖尿病的新药开发的先导结构。为了评估总体策略,以收敛的方式合成了紧密的孟买他汀类似物10。蒽醌结构单元20通过芳烃/邻苯二甲酰亚胺环化而有效地制备。在将20转化为相应的9,10-二甲氧基蒽-1-甲醛衍生物(13)之后,与锂化的芳烃(12)偶联,然后在琼斯条件下进行多次氧化,得到孟买他汀类似物10。官能化芳烃中间体的制备为通过高度区域选择性的溴化和邻位锂化反应实现的。
