    Abstract: The production of substituted tetrahydro-1,2,4-oxadiazine-3,5diones by the reaction of open-chain substituted N-( Alpha carboxy)-alkoxyureas with cyclizing agents in the form of chlorides or bromides of phosphoric acid, phosphorous acid, sulfurous acid or carbonic acid. The products of the process (some of which are new substances) are herbicides, diuretic and antiphlogistic pharmaceuticals and valuable starting products for the production of pesticides and pharmaceuticals.
