A novel and efficient domino reaction for the one-pot synthesis of spiro-2-aminopyrimidinones
摘要:
A novel and efficient protocol is developed for the synthesis of various spiro-2-amino pyrimidinones via the three-component condensation of alkyl cyanoacetates, guanidinium carbonate and N-substituted 4-piperidinones in ethanol at reflux. High yields, neutral conditions, and short reaction times are advantages of this method. (C) 2008 Published by Elsevier Ltd.
