Abstract
The reaction of 5-hydroxy-3,3,5-trimethylisoxazolidine with alkyl (or aryl) isocyanates gives N-alkyl(aryl)-carbamoyl-5-hydroxy-3,3,5-trimethylisoxazolidines, which react with methanol in the presence of p-toluenesulfonic acid to give 5-methoxy-1-carbamoyl derivatives of isoxazolidine. When arylcarbamoyl-5-hydroxy-3,3,5-trimethylisoxazolidines are heated in carbon tetrachloride, they are converted to O-arylcarbamoyl-N-(2-methyl-4-oxo-2-pentyl)hydroxylamines, the treatment of which with hydrogen chloride in benzene made it possible to isolate 1,2,6-oxadiazepin-7-ones along with the hydrochloride of the given compounds.
