Diastereoselective, multicomponent access to trans-2-aryl-4-arylamino-1,2,3,4-tetrahydroquinolines via an AA′BC sequential four-component reaction and their application to 2-arylquinoline synthesis
An efficient and practical palladium-catalyzed aerobic oxidative approach to afford functionalized 2-substituted quinolines in moderate to good yields from readily available allylbenzenes with aniline is developed. The present annulation process has high functional-group tolerance and high atom economy, making it a valuable and practical method in synthetic and medicinal chemistry. Moreover, this transformation
A Cu‐catalyzed C−H cyclization of simple anilines with ketones and DMSO as a one‐carbon source has been developed. Using an aerobicoxidative protocol, a number of ketones and anilines could be easily converted to 2‐arylquinolines, rather than 4‐arylquinolines, thus providing a highly atom‐economical and simple approach to biologically significant 2‐arylquinolines. Based on the preliminary experiments

A simple and convenient copper-catalyzed intermolecular cyclization reaction for the synthesis of quinolines from anilines and terminal acetylene esters has been developed. This methodology constructs the C–N and C–C bonds successively via a cascade process, and provides the desired products in moderate to good yields.
regioselective synthesis of β,γ-nonsubstituted 2-arylquinolines from aldehydes and arylamines has been accomplished. The deaminative cyclization is also extended to long-chain tertiary alkylamines, enabling diverse alkyl groups to be concurrently installed into the pyridine rings. This process demonstrates a new conversion pathway for the simultaneous dual C(sp3)–H bond functionalization of tertiary amines, wherein
Organic luminescent materials containing cycloalkyl ancillary ligands is disclosed, which can be used as emitters in the emissive layer of an organic electroluminescent device. The organic luminescent materials is metal complexes which comprise a new series of cycloalkyl containing acetylacetone type ancillary ligands. These novel ligands can effectively improve the lifetime of the device, change the sublimation characteristics and improve device performance. Also disclosed are an electroluminescent device and a formulation.
