Abstract
A visible light photocatalyzed cascade sulfonylation/cyclization of 1-(allyloxy)-2-(1-arylvinyl)benzenes with sulfonyl chlorides for the con-struction of sulfonated benzoxepines is developed. In the presence of Eosin Y (2.0 mol%) as a photocatalyst and Na2CO3 as a base, the reac-tions undergo smoothly to afford the seven-membered rings in good yields. This transformation features with mild reaction conditions, the use of easily accessible materials, wide substrate scope and excellent functional group tolerance.
