Copper-Catalyzed Three-Component Alkene Carbofunctionalization: C-N, C-O, and C-C Bond Formation from a Single Reaction Platform

A general system achieving three-component intermolecular carbofunctionalization of alkenes is presented, including carboetherification, carboesterification, carboarylation, and carboamination. The scope of the reaction is presented with respect to the carbon electrophile, the olefin, and the nucleophile. Furthermore, the synthesis of δ-lactams via a carboamination reaction is demonstrated in a telescoped three-step protocol.

Squarylium compound

PROBLEM TO BE SOLVED: To provide a squarylium compound which is excellent in solubility in an organic solvent and is capable of selectively absorbing light in a red to near-infrared region while transmitting light in a visible light region at a high transmittance when forming a resin cured product. SOLUTION: The squarylium compound is represented by formula (1) (R1 and R6 are each independently a substituted/unsubstituted C3 or higher branched alkyl group; R2 and R7 are each independently a substituted/unsubstituted C5 or higher linear alkyl group; R3, R4, R8 and R9 are each independently H, an organic group or a polar functional group; and ring A and ring B are each independently a substituted/unsubstituted five- or more-membered nitrogen-containing heterocyclic ring).

An efficient one pot transfer hydrogenation and N-alkylation of quinolines with alcohols mediated by Pd/C/Zn

A Pd/C/Zn mixture with alcohols has been revealed to be an efficient transfer hydrogenation system to quinolines. Furthermore, the metals mixture is able to activate alcohols as N-alkylating agents in a hydrogen autotransfer process. 1,2,3,4-Tetrahydroquinolines and N-alkylated tetrahydroquinolines from quinolines have been obtained with excellent yields in one step.
