Process for making dihydropyrimidinones |
| abstract |
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 beta -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. |
