Zinc Chloride Mediated Synthesis of 3H -Oxazol-2-one and Pyrrolo-oxazin-1-one from Ynamide

Abstract : A simple zinc chloride mediated cyclization of ynamidyl N‐carbamates or 2‐ynamidyl‐(hetero)arylcarboxylates is smoothly achieved, leading to the synthesis of useful heterocyclic scaffolds, 3H‐oxazol‐2‐ones and pyrrolo‐oxazin‐1‐ones, with good yields.
