Abstract Synthesis of 2-phenyl and 2,3-diphenylpyrroles bearing at the 4 position electronwithdrawing groups by reaction of tosylbenzylisocyanide (TosBIC) with various Michael acceptors was investigated. Sodiumhydride and n-butyllithium were used as deprotonating agents for the synthesis of monophenyl and diphenylpyrroles, respectively.
