TL;DR: The aminolysis of valyl-tRNA and N-acetyl-valyl- tRNA by Tris and diethanolamine do not follow first order kinetics with respect to the amine concentrations, but this is interpreted by the formation of a productive complex between hydroxyl groups of theAmine and structural elements of the amino-acyl-t RNA termini.

TL;DR: Ab initio molecular orbital calculations show that prereactive complexes, 5-7 kcal mol(-1) lower in energy as compared with the reactants, are formed because of hydrogen bond interaction between OH and the N/O atom of morpholine.
Abstract: Kinetics of reaction of OH radical with morpholine, a heterocyclic molecule with both oxygen and nitrogen atoms, has been investigated using laser photolysis−laser-induced fluorescence technique, i...

TL;DR: Morpholine and other cyclic imines are obtained by reacting diethylene glycol and other appropriate diols with ammonia under hydrogenating conditions in the gas phase in the presence of a catalyst which contains copper, a smaller amount of nickel and alumina as discussed by the authors.

TL;DR: A pair of iridium-catalyzed regiospecific and stereospecific reactions of the carbonates of γ-hydroxy α,β-unsaturated esters were developed and a series of 3,4-disubstituted oxazolidin-2-ones were obtained by using allylamine as a nucleophile.
Abstract: A pair of iridium-catalyzed regiospecific and stereospecific reactions of the carbonates of γ-hydroxy α,β-unsaturated esters were developed. The reaction pathways are strongly affected by the choice of amines employed. A diverse range of γ-substituted α,β-unsaturated γ-amino esters were prepared in excellent yields with various amine nucleophiles such as benzylamine, diallylamine, morpholine, aniline and N-methylaniline. Substitution at the γ-position was well tolerated, encompassing alkyl, aryl and heteroaryl substituents. Enantioenriched (E)-α,β-unsaturated γ-amino esters could also be synthesized from the corresponding enantioenriched allylic carbonates with complete chirality transfer. In sharp contrast, a series of 3,4-disubstituted oxazolidin-2-ones were obtained by using allylamine as a nucleophile.
