Pyrazolines, the well-known five-membered nitrogen-containing heterocyclic compounds, have received considerable interests in the fields of medicinal and agricultural chemistry because of their broad spectrum of biological activities. To discover more pot
Enantioselective Synthesis of Tetrahydroquinolines via One-Pot Cascade Biomimetic Reduction?
Zhao, Zi-Biao,Li, Xiang,Chen, Mu-Wang,Wu, Bo,Zhou, Yong-Gui
supporting information, p. 1691 - 1695 (2020/11/03)
A novel and efficient protocol for the synthesis of chiral tetrahydroquinoline derivatives with excellent enantioselectivities and high yields has been developed through one-pot cascade biomimetic reduction. The detailed reaction pathway includes the acid-catalyzed and ruthenium-catalyzed formation of aromatic quinoline intermediates and biomimetic asymmetric reduction.
Tandem Cyclization?Annulation of α-Acidic Isocyanides with 2-Methyleneaminochalcones: Synthesis of Pyrrolo[2,3-c]quinoline Derivatives

Tandem cyclization-annulation of tosylmethyl isocyanide and isocyanoacetate with 2-methyleneaminochalcones as aza-1,5-dielectrophiles has been successfully developed. These domino transformations feature simultaneous formation of three bonds and two rings
Visible-Light Induction/Br?nsted Acid Catalysis in Relay for the Enantioselective Synthesis of Tetrahydroquinolines
Xiong, Wenhui,Li, Shan,Fu, Bo,Wang, Jinping,Wang, Qiu-An,Yang, Wen
supporting information, p. 4173 - 4176 (2019/06/07)
An efficient method merging Br?nsted acid catalysis with visible-light induction for the highly enantioselective synthesis of tetrahydroquinolines has been developed. This mild process directly transforms 2-aminoenones into 2-substituted tetrahydroquinolines with excellent enantioselectivities through a relay visible-light-induced cyclization/chiral phosphoric acid-catalyzed transfer hydrogenation reaction.
Organocatalyzed aerobic oxidative Robinson-type annulation of 2-isocyanochalcones: expedient synthesis of phenanthridines

Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C6-C 3-C6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.
