Ring Opening Reactions of Indenoisoxazolones
Lemke, Thomas L.,Sawhney, Kailash
, p. 899 - 901 (2007/10/02)
Nucleophilic attack of 8-substituted indenoisoxazol-7-ones (1) and 3-phenylindenoisoxazol-4-one (4) by dimethylsulfoxide or triphenylphosphine results in cleavage of the nitrogen-oxygen bond of the isoxazole ring leading to the formation of sulfoximides (2 and 5) and phosphazenes (3 and 8).
