New Strategies and Transformations for the alpha-Functionalization of Amines to Access Chiral Amines
… methodologies to prepare alpha-functionalized amines, especially chiral amines have been studied in this work. Specifically, we focused our work on introducing alpha-functionalization to amines through C–C forming processes. This thesis work is inspired by the vitamin B6 transamination process: …

Interactions of halogens with amines
The individual stages of the interaction of amines with halogens - in particular, iodine - have been studied. 'In the course of this investigation, it has been shown that amines and iodine interact initially via the nitrogen lone pair to form molecular complexes (CHARGE-TRANSFER COMPLEXES). Several …

Functional polymer layers with protected amines
This work refers to the area of bio-nanotechnology and concerns the selective immobilization of DNA or other bio-template on microstructured gold contacts and which then permit a coordinated cooperation of several of these nanotemplate, e.g., within a microreactor. The immobilization of such …

Hydroamination of terminal allylic imines, allylic amines, and internal and terminal homoallylic amines: Regioselective and regiodivergent transformations
… The intermolecular hydroamination of alkenes and amines represents a novel approach towards these disconnections from readily accessible functional groups. This transformation can streamline the synthesis of complex molecules and often allows access to two regioisomers (Markovnikov and …

Asymmetric synthesis of benzylic and heterobenzylic amines
… gave the N-substituted-1-(2-pyrrolyl)alkylamines with high yields and diastereoselectivities. The (S,S)-diastereomers were useful intermediates for the preparation of enantiopure 1-[1-(2-pyrrolyl)alkyl]aziridines by routine cyclization of the β-aminoalcohol moiety and of (S)-N-benzoyl …

The palladium-catalyzed synthesis of organic amines
Chapter 1. The chelating ligand bis[2-(diphenylphosphino)phenyl] ether (DPEphos), in combination with palladium acetate, forms a highly active catalyst system for the coupling of anilines with aryl bromides. The bisphosphine is easily prepared in large quantity and at low cost by a known procedure. …

INFLUENCE OF BIOGENIC AMINES ON BOVINE LUTEAL STEROIDOGENESIS
<p>To investigate the role of catecholamines and biogenic amines in the control of bovine luteal steroidogenesis, studies were conducted utilizing collagenase-dispersed luteal cells in a short-term incubation system. Studies designed to assess the role of catecholamines showed that the stimulatory …

Aqueous reactions of ozone with primary aromatic amines
Ozone reacts readily with primary aromatic amines (aniline, 3-methylaniline, 3-chloroaniline, 4-bromoaniline, 4-nitroaniline) in dilute aqueous solutions (10$\sp{-5}$-10$\sp{-4}$ M). The major isolated reaction products identified by GC/MS were nitrosobenzenes, nitrobenzenes, azobenzenes, …

Radical methods for the synthesis of aliphatic amines
… radical reactions for the synthesis of aliphatic amines. Following an introduction to radical chemistry and a summary of previous advances in amine synthesis, chapter 2 will describe a general carbonyl alkylative amination reaction, a successful version of which has been sought for over 70 years. …
