Abstract
Abstract Trisubstituted N-benzylpyrrole derivatives were synthesized through a one-pot four-component reaction from β-keto esters, benzylamines, aromatic aldehydes, and nitromethane in the presence of 10 mol % bromodimethylsulfonium bromide (BDMS) as catalyst at room temperature. Some of the salient features of the present protocol are simple and mild reaction conditions, good yields, and applicability with a wide range of substrates.
