摘要: The present invention provides a process for forming 5-(alkyl or alkoxy)carbonyl-6-alkyl-4-(aryl or alkyl)-3,4-2(1H)-dihydropyrimidinones by combining a β-keto ester or diketone, an aldehyde and urea in the presence of a boron reagent, a metal salt (e.g., Cu2O) and a catalyst (e.g., acid). The reaction is typically run in one pot in a solvent to afford dihydropyrimidinones in higher yields and with easier work up than previously known methods.

摘要: A process of synthesizing a compound of formula (1) is described. A compound of formula (2) is reacted with diphenylphosphinic chloride to activate the carboxylic acid group, and then reacted with methanesulfonyl chloride to produce a compound of formula (4). Compound (4) is then reacted with a group II metal sulfide source in water to produce a compound of formula (1).
