Cobalt-diphosphine catalysts have been found to promote intramol. reactions between a vinylcyclopropane and an alkyne to selectively afford either the [5+2] cycloaddition product or the homo-ene reaction product under solvent control. The former product is exclusively formed in noncoordinating 1,2-dichloroethane, whereas the latter is dominant in coordinating solvents, such as acetonitrile and dimethylacetamide. Furthermore, a highly enantioselective variant of the homo-ene reaction afforded chiral THF, pyrrolidine, and cyclopentane derivatives bearing 1,3-diene and alkylidene substituents. Thus, e.g., cycloaddition of I afforded II (85%) in presence of CoI2, dppp, Zn and ZnI2 in DCE, whereas the same catalytic system exclusively afforded homo-ene product III (86%) in NMP.
