Abstract

An efficient visible-light-mediated tandem reaction of acryl­oylbenzamides with alkylboronic acids, arylsulfonyl hydrazides and oxime esters has been developed. The reaction proceeds via radical addition and cyclization to give various isoquinoline-1,3(2H,4H)-diones in satisfactory yields under mild conditions, which provides a good opportunity to discover new meaningful bioactive compounds.
