چكيده فارسي :
An efficient and simple route for preparation of polyhydroquinolines and dihydropyridines derivatives via SBA-15/SO3H catalyzed ring opening of diketene in four component Hantzch-type reactions are presented. Dihydropyridines derivatives based on neat adduct of diketene, alcohols and aldehydes using SBA-15 sulfonic acid modified mesoporous substrates, a green and reusable catalyst are also synthesized. In this paper, the present method includes some advantages such as simple procedure, waste-free, green, using small amount of catalyst, high yield of products and short reaction time
