Reaction Conditions:
in benzene at 20; for 25 h;Reflux;
Steps:
Synthesis of enaminodiones 5a-i (general procedure).
General procedure: Dimethylformamide dimethyl acetal (15.49 g, 0.13 mol) was added to 1,3-diketone 4 (0.1 mol) in anhydrous benzene (46 mL), the reaction mixture was stirred for 24 h at room temperature and then refluxed for 1 h, using a reflux condenser equipped witha calcium chloride drying tube. Then the solvent and an excess of DMF DMA were removed at reduced pressure, the residue was recrystallized from a proper solvent.
