Novel oxoisochromene synthesisviachemoselective O–H insertion of 1,3-dicarbonyl compounds and subsequent Pd-catalyzed intramolecular arylation reaction

Abstract

Chemoselective O–H insertion of 1,3-diketones under transition metal-free conditions gives rise to vinyl ethers; Subsequent Pd-catalyzed intramolecularO-arylation of vinyl ethers leads to novel oxoisochromenes.
