A novel class of fused heterocycles,benzo­[b]­furo­[2,3‐c]­pyrroles

In the isomeric compounds 2‐benzyl‐3‐methyl‐1‐phenyl­benzo­b]­furo­2,3‐c]­pyrrole and 2‐benzyl‐1‐methyl‐3‐phenyl­benzo­b]­furo­2,3‐c]­pyrrole, both C₂₄H₁₉NO, the pyrrole ring, although presumably somewhat strained, does not differ appreciably from N‐methyl­pyrrole except for a relatively short C—C single bond in the pyrrole ring.
