The Chemistry of 5-Oxodihydroisoxazoles. VI. The Photolysis of 2-Arylisoxazol-5(2H)-ones in Amines
Ethyl 5-oxo-2-phenyl-2,5-dihydroisoxazole-4-carboxylate (1) undergoes facile photolysis at 300 nm by two pathways in the presence of amines.One pathway gives an isomeric ketene which, in the presence of amines, is trapped as methanetricarboxylic acid amid

The Chemistry of 5-Oxodihydroisoxazoles. IV. Reactions of Some N-Arylisoxazol-5-ones with Nucleophiles
The reactions of ethyl 2-aryl-5-oxo-2,5-dihydroisoxazole-4-carboxylate (aryl = phenyl, isoquinolin-1-yl, 2-phenylquinazolin-4-yl and 5-nitropyridin-2-yl) with azide and primary, secondary and tertiary amines, and a number of other nucleophiles are describ

The Photolysis Of Ethyl 5-Oxo-2-Phenyl-2,5-Dihydroisoxazole-4-Carboxylate In Amines And Alcohols
Ethyl 5-oxo-2-phenyl-2,5-dihydroisoxazole-4-carboxylate (1) has been photolysed at 300 nm in a variety of alcohols and amines.The products suggest two competing photolytic pathways: reversible photoisomerisation to a ketene, and a loss of carbon dioxide t
