Facile Preparation of Spirolactones by an Alkoxycarbonyl Radical Cyclization-Cross-Coupling Cascade.

Angew Chem Int Ed Engl

Department of Chemistry, University of California, Irvine, 1102 Natural Sciences II, Irvine, CA, 92697-2025, USA.

Published: June 2019

An alkoxycarbonyl radical cyclization-cross-coupling cascade has been developed that allows functionalized γ-butyrolactones to be prepared in one step from simple tertiary alcohol-derived homoallylic oxalate precursors. The reaction succeeds with aryl and vinyl electrophiles and is compatible with heterocyclic fragments in both coupling partners. This chemistry allows for the rapid construction of spirolactones, which are of interest in drug discovery endeavors.
