Three-component strategy toward 5-membered heterocycles from isocyanide dibromides.
Kaim, Laurent El,Grimaud, Laurence,Patil, Pravin
, p. 1261 - 1263 (2011)
A three-component strategy starting from isocyanides allows a straightforward synthesis of five-membered ring heterocycles. New cascades were developed involving the addition of a nitrogenated nucleophile-an azide or a tetrazole-on isocyanide dibromides,
