Abstract
A facile and efficient one-pot synthesis of 1,3-disubstituted pyridin-2(1H)-ones is developed via a novel cascade reaction of readily available α-hydroxy-α-carbamoyl ketene S,S-acetals under Vilsmeier conditions (DMF/POCl3), and a mechanism of this domino reaction is proposed.
Key words
pyridin-2(1H)-ones - Vilsmeier reagent - α-hydroxyketene S,S-acetals
