Graphic abstract: Stereoselective one-pot synthesis of (1<i>Z</i>)- and (1<i>E</i>)-1-arylmethylidene-2,3-dihydro-1<i>H</i>-pyrrolo[1,2-<i>a</i>]benzimidazoles by cyclization of alk-4-ynals with <i>o</i>-diaminobenzene

Abstract: Cyclization of alk-4-ynals with o-diaminobenzene in DMSO under the sequential action of NH₄Br and base (KOH or K₂CO₃) affords 1-arylmethylidene-2,3-dihydro-1H-pyrrolo[1,2-a]benzimidazoles, which are formed selectively as E- or Z-isomers depending on the base used.
