Biomimetic Dehydrogenative Diels–Alder Cycloadditions: Total Syntheses of Brosimones A and B

Abstract

Passing (H2) gas: Concise syntheses of the natural products brosimones A and B have been achieved using sequential dehydrogenative Diels–Alder (DHDA) cycloadditions. The syntheses employ either Pt/C-cyclopentene or DDQ to effect dehydrogenation of prenylchalcone substrates in combination with silver nanoparticles to promote subsequent Diels–Alder cycloadditions.
