Abstract

An efficient, convergent synthesis of a differentially protected C20-C38 segment of the brasilinolides is described. Iterative 1,4-syn aldol additions and ketone reductions were employed to construct the two related stereotetrads, while a sequence of Horner-Wadsworth-Emmons (HWE) coupling, CBS reduction, and Sharpless AE installed the epoxy alcohol functionality.
