Reaction Conditions:
with uranyl nitrate hexahydrate;ammonium acetate in ethanol at 20; for 0.333333 h;Sonication;
Steps:
General procedure for synthesis of 1,4-DHPs
General procedure: To a solution of aldehyde (1.0 mmol), ethyl/methyl acetoacetate/acetylacetone (2.0 mmol) and ammonium acetate (1.0 mmol) in ethanol (3 mL), uranyl nitrate (10 mol%) was added and the resultant reaction mixture was sonicated at room temperature for the required time (Table 1). The progress of the reaction was monitored by TLC. After completion of the reaction, the mixture was poured into crushed ice. The obtained solid was filtered, washed thoroughly with water, dried, and purified by recrystallisation in ethanol.
