Heterocyclic β-Enamino Esters, 44: 2,3,3a,7a-Tetrahydrobenzofurans, -benzothiophene, and 2,3,3a,7a-Tetrahydroindole by Cycloaddition with Cyanoacetylene

With two molecules cyanoacetylene the (4,5-dihydro-2-furyl- (1a-c), -2-pyrrolinyl- (1d), and -2-thienylimino (1e))triphenylphosphoranes and the furan β-enaminonitrile 1f afford the 2,3,3a,7a-tetrahydrobenzofurans 2a-c,f, the 2,3,3a,7a-tetrahydroindole 2d, and the benzothiophene 2e, respectively.The structure of 2b is established by X-ray diffraction.
