## Abstract The present short communication describes a Lewis acid (Zn[(L)proline]~2~) catalysed one pot synthesis of Hantzsch 1,4โdihydropyridine (DHP) derivatives under solventโfree condition by conventional heating and microwave irradiation. The Lewis acid catalyst Zn[(L)proline]~2~ used in this
## Abstract Silicaโsupported polyphosphoric acid (PPAโSiO~2~) catalyzed efficiently the reaction of anthranilamide with aryl aldehydes or ketones under solventโfree conditions to afford the corresponding 1,2,3,4โtetrahydroโ4โquinazolinone derivatives. This work consistently has the advantages of ex
