The synthesis of 6,7-dihydro-5H-pyrimidinocarbazoles (3) was achived by cyclisation of 1,2,3,4-tetrahydrocarbazol-4-ones with triformamidomethane.The oxydation with potassium permanganate of 6,7-dihydro-5H-pyrimidinocarbazoles gave the 7H-pyrimidinocarbazoles (4).The reactions of the pyrimidinocarbazoles (4a) and (4e) with lithium organic compounds afforded 4-substituted derivatives (6).The structure of the derivatives was determined by (1)H-NMR and Overhauser effect.Keywords - 1,2,3,4-tetrahydrocarbazol-4-one; 6,7-dihydro-5H-pyrimidinocarbazole; 7H-pyrimidinocarbazole; (1)H-NMR; Overhauser effect
