Addition reactions of acetylenic esters to 6,7-dihydrobenzo[b]furan-4(5H)-one, 6,7-dihydroindol-4(5H)-one, 5,6-dihydrobenzo[b]furan-7(6H)-one and 5,6-dihydroindol-7(6H)-one ketoximes. Formation of reduced furo[g]- and pyrrolo[g]-indoles

Thermal rearrangement of 6,7-dihydrobenzo[b]furan-4(5H)-one and 4,5,6,7-tetrahydroindol-4-one 4(7H)-O-(E)-(1,2-dimethoxycarbonylvinyl)ketoximes gave 4,5-dihydrofuro[2,3-g]- and 4,5-dihydropyrrolo[2,3-g]- and [3,2-g]-indoles, three novel tricyclic systems.

5,6,7,8-Tetrahydrothieno[3,2-b]azepine,5,6,7,8-tetrahydro-1H-furo[3,2-b] azepine, and 1,4,5,6,7,8-hexahydropyrrolo[3,2-b]azepine were synthesized by the ring expansion reaction of heterocyclic fused cyclohexanone oximes with diisobutylaluminum hydride (DIBAH). The mechanism of the reaction was different from that of Beckmann rearrangement.
