Abstract
The preparation and properties of 3-keto-1,2,5,6-tetrahydro-3(H)-imidazo(1,2-a)imidazole, 3-keto-1,2,6,7-tetrahydro-3(H),5(H)-imidazo(1,2-a)pyrimidine, and 4-keto-2,3,6,7,8,9-hexahydro-4(H)-pyrimido(1,2-a)pyrimidine are described. The first two bicyclic systems possess active methylene groups in position 2 and they are oxidized to indigo-type dyes.Keywords
