An Improved Protocol for Biginelli Reaction
نویسنده
چکیده
Hmim][Tfa] was tested as catalyst for the Biginelli reaction multicomponent reaction under conventional and non conventional heat source i.e. Microwave heating. Low catalyst loading, reduced reaction time and operational simplicity are the main highlights of this proposed protocol. Using our proposed protocol, we tested 30 different biologically active compounds in good yield.

Simple and improved conditions have been found to carry out the Biginelli reaction for the synthesis of 3, 4-dihydropyrimidin-2(1H) - one derivatives. This synthesis was performed in the presence of 12-molybdophosphoric acid (H3PMo12O40) as catalyst. These reactions were performed under solvent free conditions with microwave irradiation as the energy source. Compared with the classical Biginell...
