Visible-light-initiated selective synthesis of thiolated-, sulfoxinated-, and sulfonated benzoxazines from N-(2-vinylaryl)amides and thiols

Abstract

This article demonstrates the utilization of blue LED to selectively synthesize thiolated-, sulfoxinated-, and sulfonated benzoxazines in good yields from a series of N-(2-vinylaryl)amides and thiols. This methodology is mild, eco-friendly, uses O2 as the oxidant, produces no harmful by-products and works without the need of additives, or catalysts.
