Abstract
An NHC-catalyzed annulation reaction of 3-halopropenals with nitrosobenzene derivatives, providing access to 2,3-disubstituted isoxazol-5(2H)-ones under mild conditions is described. This procedure represents a metal-free approach to the alternative equivalent of β-acylvinyl anions for the formation of heterocyclic compounds.
Key words
