Yield:10354-29-7 95%
Reaction Conditions:
with iron supported on copper/Zeolite Socony Mobil-5 nanocatalyst in water at 20;Sonication;Hantzsch Dihydropyridine Synthesis;
Steps:
General procedure for preparation of Hantzsch1,4-dihydropyridine (DHP) derivatives 5(a-f)
General procedure: In a typical experiment, aromatic aldehyde (1 mmol), bketoester(2 mmol), ammonium acetate (1 mmol), and Fe-Cu/ZSM-5 (3 wt%) in 2 ml water were introduced in a 20-mL heavy-walled pear-shaped two-necked flask with nonstandard-tapered outer joint. The flask was attached to a12-mm tip diameter probe, and the reaction mixture was sonicated at ambient temperature at 20 % power of the processor. After completion of the reaction (monitored byTLC, within 5-8 min), the solid product was filtered,washed with water and ethanol, dried, and recrystallized from ethanol. The supported reagent was washed thrice with water and ethanol and dried under vacuum before reuse.
