Abstract

A rhodium-catalyzed annulation between ethyl benzimidates and alpha- aroyl sulfur ylides was developed, affording a series of pyrano[4,3,2-ij]isoquinoline derivatives in moderate to good yields with good functional group compatibility. The procedure featured dual ortho-C-H functionalization and dual cyclization in one pot. The optoelectronic properties of those fused heteroarenes were tested by UV/vis and fluorescence spectrometers.

Copper-Catalyzed Synthesis of N-Fused Quinolines via C(sp3)-H Activation-Radical Addition-Cyclization Cascade

Yangang Wu, Wen Zhang, Shiyu Ma, Chuanjun Song, Junbiao Chang

Summary: In this study, a novel copper-catalyzed cyclization reaction was developed for the synthesis of pyrazolo-[1,5-a]-quinoline, triazolo-[1,5-a]-quinoline, and pyrrolo-[1,2-a]-quinoline derivatives. The reaction proceeds through di-tert-butyl peroxide-mediated C-(sp(3))-H activation, followed by cascade radical addition and cyclization, resulting in N-fused quinolines with high yields and broad functional group tolerance.

Site-Selective sp2 C-H Cyanation of Allenes via Copper-Catalyzed Radical Relay

Zhongming Cheng, Tilong Yang, Can Li, Yunshun Deng, Fangjia Zhang, Pinhong Chen, Zhenyang Lin, Shengming Ma, Guosheng Liu

Summary: This study presents a copper-catalyzed radical relay strategy for the site-selective cyanation of sp(2) C-H bonds in allenes. The reactions show broad substrate scope and remarkable functional group compatibility under mild conditions. The site-selectivity is attributed to the unique pocket created by the Cu-bound nitrogen-centered radical and the crucial hydrogen bonding between the fluoride and the hydrogen atom. Late-stage functionalization of drug-like bioactive molecules containing an allene motif becomes feasible.

Facile synthesis of chiral 2-functionalized tetrahydroquinolines via Pd/Cu-catalyzed cascade & gamma;-C(sp(3))-H arylation/C-N coupling of amides derived from amino acids and their derivatives

Dian Yu, Si-Yuan Peng, Han Wang, Qiu-Cui Zheng, Ya-Hui Ma, Dong-Yi Xiao, Qian-Li Li, Wen-Shu Wang, Xiao-Jie Cui, Fei-Xian Luo

Summary: In this work, a one-pot strategy was developed for the precise modification of amides derived from natural amino acids via Pd/Cu-catalyzed cascade γ-C(sp(3))-H arylation/C-N coupling. This strategy successfully synthesized valuable chiral 2-functionalized tetrahydroquinoline motifs with good chirality maintenance. It offers an alternative route for the synthesis of chiral tetrahydroquinolines with good regioselectivity and broad functional group compatibility for drug discovery. The methodology has also been demonstrated for the late-stage functionalization of natural products, drugs, and biomolecules.

Pd-Catalyzed Indolization/peri-C-H Annulation/N-Dealkylation Cascade to Cyclopenta-Fused Acenaphtho[1,2-b]indole Scaffold

Tienan Jin, Shin Suzuki, Hon Eong Ho, Hidenori Matsuyama, Masaki Kawata, Masahiro Terada

Summary: A novel Pd-catalyzed cascade reaction has been developed to construct a cyclopenta-fused acenaphtho[1,2-b]indole (ANI) scaffold, which can be used to synthesize pi-extended ANI derivatives with relatively narrow energy gaps. The potential applications of these ANI molecules as pi-segments in low-band-gap materials are implied by their increased HOMOs and lowered LUMOs.

3-Alkyl-2-pyridyl Directing Group-Enabled C2 Selective C-H Silylation of Indoles and Pyrroles via an Iridium Catalyst

Hui Sun, Yi Cheng, Houyun Teng, Xiaoqi Chen, Xiaokang Niu, Hao Yang, Yu-Ming Cui, Li-Wen Xu, Lei Yang

Summary: An iridium-catalyzed, directing group-enabled site selective intra- and intermolecular silylation of indoles and pyrroles with hydrosilanes has been developed under ligand-free conditions. Fine-tuning of the removable 3-alkyl-2-pyridyl directing group was crucial for achieving high yields for C2-silylated indole and pyrrole products. Scalability and further transformations of the silylation products have also been demonstrated.

Rhodium-Catalyzed Double Hydroboration of Quinolines

Ruibin Wang, Sehoon Park

Summary: In this study, a one-pot, site-and stereoselective borylative reduction of quinolines was developed to obtain a series of tetrahydroquinolines with a (enantioenriched) C(sp3)-B bond in the 4-position. Mechanistic studies revealed the Rh-mediated stepwise dearomative reduction cascade. The installed C(sp3)-Bpin unit in the 4-position was transformed to various functional groups through simple organic reactions.

How Solvents Control the Chemoselectivity in Rh-Catalyzed Defluorinated [4+1] Annulation

Shihan Liu, Lei Zhu, Tao Zhang, Kangbao Zhong, Shi-Jun Li, Ruopeng Bai, Yu Lan

Summary: Density functional theory calculations were used to investigate the chemoselectivity of Rh-catalyzed chiral C-F cleavage and gamma-site functionalization. The results indicated that the difference in chemoselectivity in methanol and isobutyronitrile solvents can be attributed to the different controlling steps involved in beta-F elimination and allene insertion. The analysis of explicit solvent models helped explain this discrepancy.

Cyanoalkylation/alkynylation of allylic alcohol through intramolecular radical 1,2-alkynyl migration

Shengnan Jin, Fan Chen, Pengcheng Qian, Jiang Cheng

Summary: A new method using DTBP as a promoter allows for the difunctionalization of alpha-aryl alpha-alkynyl allylic alcohols with alkyl nitriles, resulting in alpha-alkynyl gamma-cyano functionalized ketones. This process involves C(sp(3))-H bond cleavage of alkyl nitriles and radical 3-exo-dig cyclization, with a preference for 1,2-alkynyl migration over 1,2-aryl migration.
