摘要
In the presence of excess butylmagnesium chloride and in diethyl ether at 25-degrees-C, zirconocene dichloride is an effective catalyst precursor for the stereoselective cyclization of nonconjugated dienes containing a terminal alkoxide substituent. The products are carbocyclic rings containing adjacent vinyl and methyl substituents with trans stereochemistry.
