Synthesis of non-natural cyanthiwigin–gagunin hybrids through late-stage diversification of the cyanthiwigin natural product core

Abstract

Derivitization of natural product scaffolds produces diversely functionalized molecules for biological study and offers insight into the reactivities of complex molecular architectures. In the present study, the tricyclic framework of the cyanthiwigin natural product family was employed as a platform for late-stage diversification. The design and synthesis of several non-natural “hybrid” molecules resembling both the cyanthiwigin and gagunin natural products was accomplished, and the results of these investigations are described herein.
