ChemInform Abstract: Selenium‐Catalyzed C(sp³)—H Acyloxylation: Application in the Expedient Synthesis of Isobenzofuranones.

Abstract

Starting from simple 2‐allyl benzoic acid derivatives an intramolecular oxidative acyloxylation is developed which provides a chemoselective access to isobenzofuranone skeletons representing the core structure of phthalide natural products and offer the opportunity for further derivatization.
