Novel Process for Preparation of Oxazolonone, Benzoxazolonone.

Synthesis of oxazolonone, benzoxazolononeby using amino hydroxy compound, alkyl haloformate, trialkylamine and DMF as solvents. Herein used simple carbonylation agent such as alkylhaloformate instead of phosgene and Triphosgene. Developed novel and simple synthesis method. [ABSTRACT FROM AUTHOR]
