Visible‐Light‐Initiated Cascade Reaction of 2‐Isothiocyanatonaphthalenes and Amines under Additive‐ and External Photocatalyst‐Free and Mild Conditions

Abstract

Abstract A simple and efficient visible‐light‐initiated cascade reaction of 2‐isothiocyanatonaphthalenes and amines with ambient dioxygen as the sole oxidant under additive‐, external photocatalyst‐free and ambient conditions was developed. 38 Examples of N ‐substituted naphtho[2,1‐ d ]thiazol‐2‐amines were regioselectively constructed in good to excellent yields. magnified image
