Metal-free synthesis of 1,1-dimethyl-2,2,2-trifluoroethyl substituted quinazolinones via tandem radical cyclization of quinazolin-4(3H)-ones with 3,3,3-trifluoro-2,2-dimethylpropanoic acid

Abstract

A metal-free (NH4)2S2O8-mediated decarboxylative trifluoromethylation reaction of alkenes with 3,3,3-trifluoro-2,2-dimethylpropionic acid has been proposed. This method offers a novel route for the direct synthesis of a series of CMe2CF3-containing quinazolinones...
