We report the design of a catalytic, bifunctional template that binds heterocyclic substrate via reversible coordination instead of covalent linkage, allowing remote site- selective C-H olefination of heterocycles. The two metal centers coordinated to this template play different roles; anchoring substrates to the proximity of catalyst and cleaving the remote C-H bonds respectively. Using this strategy, we demonstrate remote site-selective C-H olefination of heterocyclic substrates which do not have functional group handles for covalently attaching templates. For instance the olefination can be an alkenylation of a 3- phenylpyridine with an acrylate alkyl ester selective for the meta position of the phenyl group with respect to the pyridine, or can be an alkenylation of a quinoline with an acrylate alkyl ester selective for the 5-position of the quinoline.

A modular indole synthesis based on an intramolecular 5-endo-dig carbocupration starting from readily available N-aryl-ynamides Is reported. A variety of ynamides are converted to indoles in moderate to good yields and with varying substitution pattern on the indole ring. This further extends the synthetic utility of ynamides in organic synthesis and provides additional insights on the use of intramolecular carbometalation reactions.

A general procedure for the palladium-catalyzed annulation of substituted haloanilines with norbornadiene gives functionalized indolines in 51-98% yield. These indolines can be rapidly converted to benzenoid-substituted indoles and tricyclic indolines. Extension to the use of substituted halobenzamides gives functionalized isoquinolinones in up to 86% yield.
