SELENONIUM MONOKETOYLIDES IN THE SYNTHESIS OF 4- and 5-SPIROISOXAZOLIDINES

Magdesieva, N. N.,Sergeeva, T. A.

, p. 1382 - 1386 (2007/10/02)

Preparative methods have been developed for the synthesis of 4- and 5-spiroisoxazolidines by the reaction of C-benzoyl-N-phenylnitrone with methylenecycloalkanes and 2-arylmethyleneindanediones.The reaction of the nitrone with methylenecycloalkanes proceeds with steric specifity.Two epimeric isoxazolidines are formed in the presence of a substituent in the phenyl ring of the arylmethyleneindanedione.
