Biosynthetically-inspired oxidations of capillobenzopyranol

Org Biomol Chem. 2017 Jun 7;15(22):4811-4815. doi: 10.1039/c7ob00868f.

Abstract

The synthesis of verrubenzospirolactone from its proposed biosynthetic precursor, capillobenzopyranol, has been shown to be chemically feasible via a simple reaction sequence. The key steps are a chemoselective furan oxidation mediated by NaClO2, a stereoselective dehydration of a γ-methoxybutenolide, and an intramolecular Diels-Alder reaction.
