Visible light-induced difunctionalization of electron-enriched styrenes: synthesis of tetrahydrofurans and tetrahydropyrans†
Abstract
The difunctionalization of electron-enriched styrenes for the synthesis of substituted tetrahydrofurans and tetrahydropyrans in the presence of photoredox catalysts is described. The procedure is highlighted by its operational simplicity, low catalyst loadings (1 mol%), excellent stereoselectivity and mild reaction conditions.
