Dihydropyrimidine synthesis
WebAn FGFR4 inhibitor taking 3,4-dihydropyrimidine[4,5-d]pyrimidine-2(1H)-ketone as a mother nucleus and having a covalent structure. Compounds such as LX01, LX05, LX06, LX07, and LX08 can only be covalently bound to Cys552 in the FGFR4 and cannot be covalently bound to Cys477 in the FGFR4, while a compound LX09 can be covalently … WebAbstract. In 1893, P. Biginelli reported the synthesis of functionalized 3, 4-dihydropyrimidin-2 (1H)-ones (DHPMs) via three-component condensation reaction of an aromatic aldehyde, urea, and ethyl acetoacetate. In the past decade, this long-neglected multicomponent reaction has experienced a remarkable revival, mainly due to the interesting ...
