Treatment of a series of hydroxamic acids 2 with mesyl chloride in the presence of 2 equiv of triethylamine at 0 deg C gives 2-chloroamides 3 in good yields.Use of a single equivalent of triethylamine gives the N-(mesyloxy)amides 1, which are versatile sy

Certain reactions of nitrone 1 and isocyanide 2, in the presence of ether-boron trifluoride, afford 4-imidazolidinones 4 which have been shown to be ring expansion products of the 4-imino-1,2-oxazetidines 3. 1,2,4-Oxadiazolidin-5-ones 5 (rather than 3 or
The Thermal Decomposition of N,O-Diacyl-N-t-butylhydroxylamines. IV. A Novel Acyloxyl Migration in N,O-Diacyl-N-t-butylhydroxylamines

Several N,O-diacyl-N-t-butylhydroxylamines were prepared, and their thermal decompositions were studied.N-Propionyl-O-benzoyl-N-t-butylhydroxylamine gave N-t-butyl-2-benzoyloxypropanamide, together with the decomposition products, N-t-butylpropanamide and benzoic acid, upon thermal decomposition in tetralin.Similar benzyloxyl migrations were found in the thermal decomposition of N-butyryl, N-valeryl, and N-(3-phenylpropionyl) derivatives.
