“…1,4‐Dihydropyridine and related derivatives are found to possess significant pharmacological efficacies that include anti‐tumor, anti‐tubercular, anti‐thrombotic, anti‐inflammatory etc activities. Abaszadeh et al . employed nano‐zinc oxide as an efficient heterogeneous catalyst for the synthesis of 1,4‐dihydropyridine ( 70 ) starting from aromatic aldehydes ( 1 ), malononitrile ( 34 ) and cyclic enaminoketones ( 69 ) under the influence of ultrasonic irradiation in ethanol at 80 °C (Table ).…”

The nano-sized catalysts are more effective than the traditional homogeneous or heterogeneous catalysts in bulk state. On the other hand, ultrasound-assisted strategy offers several advantages such as higher reaction rates, better yields, cost effective, environmentally benign as compared to traditional methods.Therefore, a fruitful combination of nano-catalyst and ultrasound is one of the effective tools to carry out diverse organic transformations. The present review deals with the latest developments on various nano-particles catalyzed organic synthesis under the influence of ultrasonic irradiation.

“…Therefore, we continue our investigation for improving the efficiency, eco-friendliness and green approach for the synthesis of various heterocycles. [35][36][37][38] In recent past, we have stated few methodologies for the synthesis of different medicinal stimulating molecules. [39][40][41][42][43][44] The current investigation lays emphasis on the synthesis of novel citric acid doped MCM-48 solid material which was applied as a catalyst for the first time, and also its use in the synthesis of novel quinolines by the reaction of aromatic aldehydes, malononitrile, 5,5-dimethylcyclohexane-1,3-dione and ammonium acetate at room temperature with EtOH as green solvent in excellent yields.…”

A facile, efficient and suitable green approach has been designated for the one‐pot synthesis of quinoline derivatives in the presence of citric acid doped MCM‐48 (CAMCM‐48) as a heterogeneous catalyst. The prepared material was characterized by using various techniques like P‐XRD, SEM, TEM, TGA, FTIR and structural properties was determined by BET analysis. The reaction progressed efficiently under ethanol solvent system at room temperature condition to afford the corresponding products. This protocol offers many advantages such as simple synthesis, easy work‐up, short reaction times (15 min), good stability, reusability and no chromatographic separation techniques plus excellent yields (91‐98%).

Mono and bis 4,pyran derivatives were synthesized by three-component reaction of aromatic aldehydes, malononitrile and 4-hydroxycoumarin or 4-hydroxy-6-methylpyrone, in the presence of catalytic amounts of sodium benzenesulfinates, as a organocatalyst, in H 2 O/EtOH, at reflux. High conversions, short reaction times, cleaner reaction profiles and usage of a stable and also inexpensive catalyst are some of the advantages of this method.
