Five fully functionalized N,N'-(1,3-propane)bispyrroles were synthesized by the tert-butyl isocyanide-mediated one-pot reaction of bisimines, aroyl chloride and dimethyl acetylenedicarboxylate under ultrasonic irradiation in good yield. The structures of N,N'-(1,3-propane)bispyrroles were characterized by H-1 NMR and C-13 NMR spectroscopy.

Open‐chain bis‐Reissertcompounds 1 were converted to the corresponding bis‐oxazolium intermediates via acid‐catalyzed intramolecular cyclization. These oxazolium compounds exist in a variety of tautomeric structures in which the meso‐ionic form can be intercepted by reaction with dipolarophiles in a 1,3‐dipolar‐cycloaddition reaction to produce a variety of highly functionalized bis‐pyrrole esters
