Cyclic Carbonylation of Glycolohydroximic Esters to 3-Alkoxy-4H-1,5,2-dioxazine-6-ones
Reactions of the (E)-2-hydroxy carbohydroximic esters 3 with trichloromethyl chloroformate produce the 3-alkoxy-4H-1,5,2-dioxazine-6-ones 4.Treatment of 4c with benzylamine gives compound 5, and methanolysis of 4c affords the carbonate 7.
