✦ Synopsis

Eingegangen am 18. Marz 1986 Die (4,5-Dihydro-2-furyl-(1 ac), -2-pyrrolinyl-(1 d) und -2-thienylimino (1 e))triphenylphosphorane und das Furan-P-enaminonitril 1 f ergeben mit zwei Molekiilen Cyanacetylen die 2,3,3a,7a-Tetrahydrobenzofurane 2a -c, f, das 2,3,3a,7a-Tetrahydroindol 2d sowie das Benzo[b]thiophen 2e. Die Konstitution von 2b wird durch Rontgenstrukturanalyse ermittelt. Heterocyclic fi-Enamino Esters, 44 2,3,3a,7a-Tetrahydrobenzofurans, -benzo[l]thiophene, and 2,3,3a,7a-Tetrahydroindole by Cycloaddition with Cyanoacetylene With two molecules cyanoacetylene the (4,5-dihydro-2-furyl-(1 a -c), -2-pyrrolinyl-(1 d), and -2-thienylimino (1 e))triphenylphosphoranes and the furan p-enaminonitrile 1 f afford the 2,3,3a,7a-tetrahydrobenzofurans 2a -c, f, the 2,3,3a,7a-tetrahydroindole 2d, and the benzo[b]thiophene Ze, respectively. The structure of 2 b is established by X-ray diffraction.
