A short biomimetic approach to the fully functionalized bicyclic framework of type A acylphloroglucinols

Org Lett. 2009 Oct 1;11(19):4430-3. doi: 10.1021/ol901781n.

Abstract

A biomimetic approach toward type A polyprenylated acylphloroglucinols (PPAPs) is described. The method is based on a C-alkylation-cation cyclization reaction sequence, leading to a convenient buildup of molecular complexity, employing the simple and readily available deoxycohumulone and an appropriately functionalized hydroxy halide. Thus, a versatile construction of the fully functionalized bicyclic framework of type A PPAPs (5) was achieved.
