An efficient synthesis of a range of 1,2-benzisoxazoles using an improved 1,3-dipolar cycloaddition of nitrile oxides and benzyne is described. Key to the procedure is the in situ generation of the reactive nitrile oxide and benzyne reaction partners medi

An efficient protocol for the synthesis of a range of 1,2-benzisoxazoles using an improved 1,3-dipolar cycloaddition of nitrile oxides and benzyne is described. Key to the procedure is the in situ generation of the reactive nitrile oxide and benzyne reactants simultaneously. The Royal Society of Chemistry 2010.

It is shown that the syn oximes of o-iodo- and o-, m-, and p-bromobenzophenones, under the influence of K2S2O8 in concentrated H2SO4, form the corresponding 3-aryl-1,2-benzisoxazoles as a result of oxidative cyclization. 3-(2-Iodophenyl)-1,2-benzisoxazole is oxidized by peracetic acid to the iodoso derivative which, upon heating in concentrated H2SO4, undergoes cyclization to the 4,2'-iodonia-3-phenyl-1,2-benzisoxazole cation.The iodide, bromide, and tetrafluoroborate of this cation were isolated.
