A convenient method for the synthesis of 3-carbamoyl-1,2,4-oxadiazoles from carbamoyl-amidoximes and chlorides or anhydrides of haloacetic acids was developed. The reactions of 3-carbamoyl-5-trichloromethyl-1,2,4-oxadiazoles with amines and N,N-dimethylhydrazine were studied.
A convenient procedure was developed for the synthesis of carbamoylamidoximes by the reaction of N(S)-substituted monothiooxamides with hydroxylamine hydrochloride in pyridine.
