However, 1 q afforded the seven-membered cyclic amidine 2 q, thus smoothly reflecting the prominent template effect of a ring. Finally, we draw attention to the divergent results presented by the close homologues 4 p,q and 1 r. The observation that such a subtle change in nucleophilicity can confer so remarkable a divergence in the reaction courses is amazing. In summary, a new ketenimine reaction mode has been established and thus provides a convenient copper-catalyzed protocol for cyclic amidine synthesis with high yield under mild reaction conditions.
By using this method, tertiary allyl enynes, with broad substitution patterns, can be converted stereoselectively into a-allyl cyclic amidines bearing multiple functionalities for potential elaboration.
