[(IPr)AuCl]-Catalyzed Formal [4+2] Process of N-Ar N,O-acetals with Arylacetylenes for Construction of Pyrrolo[1,2-a]quinolines

An efficient approach to access functionalized pyrrolo [1,2-a]quinolone skeleton was developed through [(IPr)AuCl]-catalyzed formal intermolecular [4+2] reaction of N-Ar N,O-acetals 6a-6h with arylacetylenes 7a-7r. As a result, a series of...
