An iron-catalyzed domino reaction of donor–acceptor cyclopropanes: a diastereoselective approach towards diversely functionalized pyrrolo-quinazolines

Autor: Samiran Dhara, Subhadeep Ghosh, Asish R. Das

Publikováno v: Organic & Biomolecular Chemistry. 20:1415-1424

An expeditious synthetic route to access functionalized pyrrolo[2,1-b]quinazoline scaffolds has been achieved via domino ring opening cyclization (DROC) reactions of donor–acceptor (D–A) cyclopropanes and 2-amino(methyl)aniline derivatives.
