Preparation of benzolactams by Pd(II)-catalyzed carbonylation of N-unprotected arylethylamines [PDF]

, 2014
An unprecedented NH2-directed Pd(II)-catalytic carbonylation of quaternary aromatic α -amino esters to yield 6-membered 10 benzolactams has been developed. The reaction shows a strong bias to 6-membered lactams over 5-membered ones.

Effect of pH on the Transient Reduction of Pig-Plasma Benzylamine Oxidase by Benzylamine Derivatives [PDF]

European Journal of Biochemistry, 1976
1. The transient kinetics of reduction of the 470-nm absorption band in benzylamine oxidase by substrate at different pH values between 6 and 10 have been studied by stopped-flow techniques, and substituent effects on kinetic parameters for the reduction process have been examined using a series of ring-substituted benzylamine derivatives as the ...

Efficient Photocatalytic Selective Oxidation of Benzylamines over Cobalt Molecular Catalyst Covalently Bonded to Carboxyl Functionalized Carbon Nitride

Advanced Energy & Sustainability Research, 2023
Photocatalysis is accepted as a promising method for selective oxidative coupling of amine to imine. However, owing to the rapid dehydrogenation of the generated imine intermediate of α‐amino hydrogen to butyronitrile, it remains a huge challenge to ...

A Noncovalent Click‐to‐Release Strategy to Control Bond Cleavage and Prodrug Activation

Angewandte Chemie, EarlyView.
Extending the click‐to‐release concept beyond covalent ligation, we introduce a noncovalent click‐to‐release strategy based on cucurbituril‐adamantane (CB‐Ad) association. A supramolecular preassembly encapsulating a self‐immolative guest (SIG) is rationally designed to prevent premature release, while adding a high‐affinity Ad guest initiates the CB ...

A Novel Indium-Catalyzed Three-Component Reaction: General and Efficient One-Pot Synthesis of Substituted Pyrroles [PDF]

, 2011
A convenient and general approach towards the synthesis of substituted pyrroles from propargylic acetates, silyl enol ethers, and primary amines was described. This novel transformation was catalyzed by indium trichloride in a one-pot synthesis, and high

Photochemical N‐dealkylation of Tertiary Amines Coupled With Photocharging of Poly(Heptazine Imides)

Angewandte Chemie, EarlyView.
Protonated poly(heptazine imide) (H‐PHI) functions as an energy reservoir, thereby facilitating the endothermic dealkylation of triethylamine through a proton‐coupled two‐electron transfer (PC2ET) process. The extent of photocharging is quantitatively described by a molecular‐level descriptor, Ne:Nhept, providing a direct correlation between stored ...

Metal-organic frameworks as selective or chiral oxidation catalysts [PDF]

, 2014
Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990s, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous ...
