Synthesis of the naturally occurring prenylated coumarins balsamiferone and cedrelopsin by domino reactions

Abstract

Regioselective one step synthesis of naturally occurring prenyl coumarin balsamiferone is described using domino Wittig reaction, 3,3-sigmatropic rearrangements and deprenylation, while regioselective synthesis of cedrelopsin is described via domino Wittig reaction, prenylation and deprenylation. © ARKAT-USA, Inc.
