    mesoporous solid acid catalysts, 3, which has a hydrophobic/hydrophobic balance in the nanospaces (mesochannels) in which the active sites are located, is found to be a significantly more selective catalytic system in the Biginelli reaction; it produces the corresponding 3,4‐dihydropyrimidin‐2‐one\thione (DHPM) 5 derivatives in good to excellent yields and excellent selectivities. Notably, in the case

    In many chemical processes, Lewis acids and bases are used to activate reactants simultaneously or sequentially. The integration of both Lewis base and Lewis acid has great potential to enhance known reactivity and drive the development of new chemical reactions with high value. In this topic, we disclose herein, the synthesis of 3,4- Dihydropyrimidin-2(1H)-ones, via one-pot three-component Biginelli condensation, in the presence of Lewis acid/ tertiary amine as a novel cooperative catalytic system. The high activity and the synergistic effect of this system are well pronounced.

    日期:2007.7
    A simple and effective synthesis of 3,4-dihydropyrimidin-2(1H)-one and 3,4-dihydropyrimidine-2(1H)-thione derivatives has been developed on the basis of three-component condensation of substituted aromatic and heterocyclic aldehydes, methyl acetoacetate, and urea or thiourea in the presence of 10% of an acidic task-specific ionic liquid ([C(4)mim][HSO4]) as catalyst under microwave irradiation in the absence of a solvent. The proposed procedure ensures short reaction times (4.4-8 min) and good yields after purification by recrystallization.
