An Alkynyliodide Cycloaddition Strategy for the Construction of Iodoisoxazoles
摘要:
The thermally promoted cycloaddition between alkynyliodides and nitrite 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.
