摘要:

报道了一种天然α-葡萄糖苷酶和人癌细胞的双效抑制剂Penasulfate A的汇聚式合成新方法. 以烯烃复分解反应、 TEMPO催化氧化、 Mitsunobu反应、 亚铜盐催化偶联反应和Julia烯烃化反应等为主要反应, 通过最长线性10步总收率13.2%完成了Penasulfate A的全合成, 优于之前合成路线的最长线性14步总收率8.6%. 研究结果为Penasulfate A及其类似物的大量合成提供了一个可参考的策略, 也为Penasulfate A及其衍生物活性的深入研究创造了条件.

关键词: α-葡萄糖苷酶, 抑制剂, 偶联反应, 烯烃复分解反应

Abstract:

α-Glucosidase inhibitors possess broad applications in terms of antidiabetes, anticancer, antivirus, therapy of obesity and so on. In this work, a new convergent synthetic route of Penasulfate A which is a dual inhibitor against α-glucosidase and human cancer cell lines was presented. Olefin cross-metathesis(CM), TEMPO-catalyzed oxidation, Mitsunobu reaction, copper(I)-salt catalyzed coupling reaction and Julia olefination reaction were leveraged as the key steps. The total synthesis of Penasulfate A has been completed over 10 longest linear steps with an overall yield of 13.2%, better than the previous route in which the title compound was synthesized in 14 linear steps with an 8.6% overall yield. This provides the candidate protocol for the syntheses of Penasulfate A and its analogues, along with the possibilities for the deeply investigation on their biological activities.

Key words: α-Glucosidase, Inhibitor, Coupling reaction, Olefin cross-metathesis reaction
