    • We monitored these reactions by TLC and quenched the reaction when the starting material disappeared. Therefore, the results described in Tables 1 and 2 would reflect the difference of the reactivity of the enynes to some extent.

    • The rate of the reaction may also be controlled by the steric effect. The lower yields of the products in the reaction of (E)-enynes may be explained in terms of the formation of polymeric compounds.

    • note
    • Though the C-2 carbon is most activated by the field effect of the electron-withdrawing group attached to the C-2 position (Figure 1 (a), no intermolecular C-C bond between C-2 carbons was formed in the zipper annulation.
