Abstract
In the presence of excess butylmagnesium chloride and in diethyl ether at 25-degrees-C, zirconocene dichloride is an effective catalyst prec ursor for the stereoselective cyclization of nonconjugated dienes cont aining a terminal alkoxide substituent. The products are carbocyclic r ings containing adjacent vinyl and methyl substituents with trans ster eochemistry.
