Facile construction of trifluoromethyl-azirines via one-pot metal-free Neber reaction

Add time:07/26/2019    Source:sciencedirect.com

A Et3N-mediated Neber reaction of aryl/alkyl-2,2,2-trifluoroethylketoximes has been developed. This one-pot metal-free protocol enables the facile construction of an array of trifluoromethyl-substituted azirines in moderate to high yields under mild reaction conditions. Further transformations of azirines to CF3-containing pyrrole and amino-alcohol derivatives are also demonstrated.
