We report herein a rare-earth-metal-catalyzed insertion of a 2-pyridine C(sp2)?H bond into an intramolecular unactivated vinyl bond. This reaction provides streamlined access to a range of azaindolines in moderate to excellent yields. The salient features of this reaction include simple and mild reaction conditions, 100% atom efficiency, and wide substrate scope. This methodology is also used to construct other nitrogen-containing compounds such as naphthyridine derivatives. A plausible mechanism for the formation of azaindolines involving initial C?H bond activation by the lanthanide complex followed by C=C insertion into a Ln?C bond to form an alkyl lanthanide species that subsequently undergoes cyclization is proposed.

An unprecedented cheap, mild and easy methodology for an intramolecular Minisci reaction based on a hydrogen atom transfer (HAT) initiated hydrofunctionalization of olefins was developed. The method is suitable for the construction of unusual dihydropyrano-pyridine and 1,2,3,4-tetrahydronaphthiridine structures and, unlike most similar reactions, does not require exclusion of air from the reaction medium.

The chemoselectivity of hydrodechlorination in 2-chloropyridine derivatives possessing reduction-sensitive functionalities is examined. The reaction conditions employed tolerate a variety of functionalities illustrating highly chemoselective hydrodechlorination in the presence of nitrile, allyl, terminal olefin, and nitroamine functionalities in excellent yield. Chemoselective deprotection of carboxybenzyl ethers is illustrated in moderate yield.
