METHOD OF PRODUCING TERTIARY AMINE OR TERTIARY AMINE DERIVATIVE
PROBLEM TO BE SOLVED: To provide a method of producing tertiary amine or tertiary amine derivative with high selectivity. SOLUTION: In the method of producing tertiary amine or tertiary amine derivative, a reaction system including: an organic chemical raw material containing at least one kind of group selected from -NH2, -NH2 HCl, >NH and >NH HCl, a nitrogen atom contained in the group bounding to a carbon atom; aliphatic alcohol having 1 to 20 carbon atoms; and a catalyst where a carrier containing titanium oxide carries a silver component (metal silver or silver compound), is irradiated with light, and the group in the organic compound raw material is converted to -NR02 or >NR0, ( R0 is an aliphatic hydrocarbon group having 1 to 20 carbon atoms derived from the aliphatic alcohol). The percentage content of the silver in the catalyst is 0.5 to 10 mass% with respect to the titanium oxide. COPYRIGHT: (C)2015,JPOandINPIT

PROCESS FOR MAKING TERTIARY AMINOALCOHOL COMPOUNDS
A process for making a tertiary aminoalcohol compound is disclosed. The process comprises using an excess amount of a carbonyl compound in a condensation step between the carbonyl compound and a nitroalkane in the presence of a catalytic amount of a tertiary aminoalcohol compound, and conducting a hydrogenation/alkylation step to produce the tertiary aminoalcohol. The tertiary aminoalcohol compound used to catalyze the condensation step is preferably the same tertiary aminoalcohol compound produced in the hydrogenation/alkylation step. The process uses fewer steps than conventional processes.

Substituted heteroarylpiperidine derivatives as melanocortin-4 receptor modulators
The present invention relates to substituted heteroarylpiperidine derivatives as melanocortin-4 receptor modulators. Depending on the structure and the stereochemistry the compounds of the invention are either selective agonists or selective antagonists of the human melanocortin-4 receptor (MC-4R). The agonists can be used for the treatment of disorders and diseases such as obesity, diabetes and sexual dysfunction, whereas the antagonists are useful for the treatment of disorders and diseases such as cancer cachexia, muscle wasting, anorexia, anxiety and depression. Generally all diseases and disorders where the regulation of the MC-4R is involved can be treated with the compounds of the invention.

Hemilabile Ligands in Organolithium Chemistry: Substituent Effects on Lithium Ion Chelation
The lithium diisopropylamide-mediated 1,2-elimination of 1-bromocyclooctene to provide cyclooctyne is investigated using approximately 50 potentially hemilabile polyethers and amino ethers. Rate laws for selected ligands reveal chelated monomer-based pathways. The dependence of the rates on ligand structure shows that anticipated rate accelerations based on the gem-dimethyl effect are nonexistent and that substituents generally retard the reaction. With the aid of semiempirical and DFT computational studies, the factors influencing chelation are discussed. It seems that severe buttressing within chelates of the substitutionally rich ligands precludes a net stabilization of the chelates relative to nonchelated (η 1-solvated) forms. One ligand-MeOCH2CH2NMe 2-appears to promote elimination uniquely by a higher-coordinate monomer-based pathway.
