An alkynyliodide cycloaddition strategy for the construction of iodoisoxazoles.

James A Crossley1, Duncan L Browne.   

Abstract

The thermally promoted cycloaddition between alkynyliodides and nitrile oxides is reported. The process offers excellent regioselectivity and a broad scope with respect to both the iodoalkynes and chloro-oximes. Further functionalization of the highly decorated iodoisoxazole motifs can be achieved via Suzuki cross-coupling.
