A new protocol for the synthesis of 2-substituted quinolinesfrom 2-aminostyryl ketones has been developed using iodide as a nucleophilic catalyst. Conjugate addition of iodide to 2-aminostyryl ketones yielded the corresponding β-iodoketones, which could have a conformation where the amino and carbonyl groups are proximal through free rotation about the Cα–Cβ single bond. Subsequent condensation between

This study reports a nickel-catalyzed sustainable synthesis of polysubstitutedquinolines from α-2-aminoaryl alcohols by a sequential dehydrogenation and condensation process that offers the advantages of a low catalyst loading and wide substrate scope. In contrast to earlier reported methods, this strategy allows the use of both primary as well as secondary α-2-aminoaryl alcohols in combination with
An efficient method for accessing arylpyridines and arylquinolines via visiblelight-inducedaerobic C–N bond activation is described. The applicability of different kinds of simple ketones, easily available amines, and the use of air as the sole oxidant make this transformation very attractive.

The first example of the transition-metal-catalyzed direct intermolecular C–H bond addition to ketones was achieved by using a rhodium catalyst. A significant influence of the directing group on the reactivity was observed, and sterically more hindered directing groups could promote the reaction. In addition, intermolecular hydrogen bonding played a role in stabilizing the product. The substrate scope
