Abstract
The Ni-catalyzed [3+2+2] cocyclization between ethyl cyclopropylideneacetate (1) and 1,3-diynes afforded cycloheptadiene derivatives. The three-component reaction of 1, 1,3-diynes, and alkynes proceeded with good yield and high selectivity. Scope of the substrates was studied, and the origin of chemo- and regioselectivity of the reaction is discussed.
