Sulfinic Acids

Methods for the synthesis of 3-phenylsulfonylcoumarins by radical sulfonylation cyclisation of phenyl propiolates with sulfinic acids or sodium sulfinates as sulfonyl sources have been developed. A combination of potassium persulfate as oxidant and silver nitrate as catalyst, or tert-butyl hydroperoxide as oxidant and potassium iodide as catalyst were used. The products were formed by an ipso-cyclisation/1,2-ester migration mechanism. The toleration of functional groups is broad and the yield is up to 96%.

Oxidative Amidation

A one-pot two-step oxidative process using tert-butyl hydroperoxide (TBHP) mediated transformation of aldehydes and amines into amides catalyzed by Copper (I) - Iodide and N-heterocyclic carbenes is developed. The process utilized is additive-free, which does not require the amines to be transformed into their hydrochloride salts. The method reported herein is facile and practicable, has a broad substrate scope, and also utilizes the economic, feasible, and abundant reagents.
