    • 7 we consider that there is considerable uncertainty about the stereochemistry and even the mechanism of the Pd-catalyzed Zn-ene cyclization; see below.

    • note
    • Limitations of this cyclization procedure became evident when attempts to cyclize the analogues of 3 bearing methyl groups on either terminus of the nonallylic alkene were unsuccessful. It is conceivable that special reaction conditions such as those required in a literature synthesis of (-)-erythrodiene (see below) would be successful. Other conditions were not tried.

    • Stereochemistry is assumed on the basis of the results in Scheme 3 and the reported structures of all other kinetic products of metallo-ene cyclizations using main group organometallics.
