Internal Oxidant‐Triggered Aerobic Oxygenation and Cyclization of Indoles under Copper Catalysis.
TL;DR: In this paper, a pyrazolo[1,5-a]indole derivatives by copper-catalyzed aerobic oxygenation and cyclization of indoles with oxime acetates is described.

Efficient 2-sulfolmethyl quinoline formation from 2-methylquinolines and sodium sulfinates under transition-metal free conditions.
TL;DR: An efficient procedure for 2-sulfolmethyl quinoline preparation from 2-methylquinolines and sodium sulfinates under transition-metal free conditions is described and these products were well tolerated to give the corresponding products in good to high yields.

Efficient pyrido[1,2-a]benzimidazole formation from 2-aminopyridines and cyclohexanones under metal-free conditions
TL;DR: An efficient procedure for pyrido[1,2-a]benzimidazole preparation from 2-aminopyridines and cyclohexanones under metal-free conditions is described in this article.

Efficient 2-Sulfolmethyl Quinoline Formation from 2-Methylquinolines and Sodium Sulfinates under Transition-Metal Free Conditions.
TL;DR: A series of 2-sulfonylmethyl quinolines (III and (V) is readily prepared by a sulfonylation of corresponding 2-methylquinolines with sodium sulfinates in the presence of tBuOOH and KI as mentioned in this paper.

Copper-catalyzed efficient direct amidation of 2-methylquinolines with amines.
TL;DR: A novel Cu-catalyzed direct amidation of 2-methylquinolines with amines is described, which afforded an efficient approach for the synthesis of biologically important aromatic amides from readily available coupling partners using molecular oxygen as the oxidant.
