A novel polyheterocyclic chemical space, 6H-furo[3,2-f]pyrrolo[1,2-d][1,4]diazepine, was generated by a one-pot four-component coupling reaction where multiple bonds (three C-C, one C-O, and one C-N) were formed through a domino sequence. Two heterocyclic rings (furan and diazepine) were sequentially constructed from the monocyclic pyrrole derivative under environment-friendly reaction conditions to furnish the tricyclic fused scaffold.

A three-component coupling protocol has been developed for the generation of 3-oxo-3-(hetero)arylpropanenitriles via a carbonylative palladium-catalyzed α-arylation of tert-butyl 2-cyanoacetates with (hetero)aryl bromides followed by an acid-mediated decarboxylation step. Through the combination of only a stoichiometric loading of carbon monoxide and mild basic reaction conditions such as MgCl2 and dicyclohexylmethylamine for the deprotonation step, an excellent functional group tolerance was ensured for the methodology. Through the use of 13C-labeled carbon monoxide generated from 13COgen, the corresponding 13C-isotopically labeled β-ketonitriles were obtained, and these products could subsequently be converted into cyanoalkynes and 3-cyanobenzofurans with site specific 13C-isotope labeling.
