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
