摘要：
Six alkenyl trichloroacetates were heated in 1,2-dichloroethane as solvent in the presence of 30% of the Cu(I)Cl/2,2'-bipyridine complex as catalyst at temperatures between reflux and 190-degrees-C (sealed tube) to effect cyclization via a chlorine transfer process providing 8- and 9-membered lactones in moderate to good yields.
