N-(Quinolin-8-yl)quinoline-2-carboxamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the title compound, C19H13N3O, the dihedral angle between the two quinoline systems is 11.54 (3)°. The molecular conformation is stabilized by intramolecular N—H...N and C—H...O hydrogen bonds, with N—H...N being bifurcated towards the two N atoms of the two quinoline rings.

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis

Angewandte Chemie, EarlyView.
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Quinolin-3-amine [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the crystal structur of the achiral title compound, C(9)H(8)N(2), N-H⋯N hydrogen bonds connect the mol-ecules into zigzag chains in [100]. Weak inter-molecular N-H⋯π inter-actions further consolidate the crystal packing.

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries

Angewandte Chemie, EarlyView.
This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

Angewandte Chemie, EarlyView.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

Quinoline-2-carbonitrile [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
In the title compound, C(10)H(6)N(2), the mol-ecule is almost planar, with an r.m.s. desviation of 0.014 Å. The dihedral angle between the aromatic rings is 1.28 (16)°. In the crystal, mol-ecules are stacked along the axis by way of weak aromatic π-π stacking inter-actions between the benzene and pyridine rings of adjacent mol-ecules [centroid-centroid

Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

Advanced Science, EarlyView.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...
