Abstract
Reaction of 2-acylcyclohexane-1,3-diones with 5- and 6-membered cyclic azomethines (3,4-dihydro-2H-pyrrole and 2,3,4,5-tetrahydropyridine) furnished derivatives of 2,3,3a;,4,8,9-hexahydropyrrolo[1,2-a]quinoline-5,6(1H,5aH)-dione and 3,4,4a,5,9,10-hexahydro-1H-pyrido[1,2-a]quinoline-6,7(2H,8H)-dione respectively. In reaction with 7-membered 3,4,5,6-tetrahydro-2H-azepine we failed to isolate polycyclic nitrogen-containing products.
