into the amino alcohol product of the method, the method involves reacting glycerol with a metal catalyst to obtain hydroxyacetone, dihydroxyacetone, and that the reaction to obtain the compound with an amine adduct using a reducing agent and reducing said adduct to obtain an amino alcohol product...
摘要: PURPOSE: To quantitatively obtain the compound by adding an optically active D-3-acetylthio-2-methylpropanoic acid chloride, L-proline and a silyl chloride compound to an aprotic solvent and subsequently further dropwisely adding an organic tertiary amine....
A process for producing one selected stereoisomer of a substituted alcohol comprises reacting a stereoisomeric amine with a halogen-substituted heterocyclic compound, or a stereoisomeric ketone or aldehyde with an amino-substituted heterocyclic compound. The process avoids the production of a racemic ...
amide or thioester of formic acid to carbon dioxide and corresponding alcohol, amine or thiol by a formate dehydrogenaseCleavage of esters, amides or thioesters of formic acid, comprises converting ester, amide or thioester of formic acid to carbon dioxide and corresponding alcohol, amine or thiol...
Chemoenzymatic synthesis of amylose-grafted poly(vinyl alcohol) In this study, we synthesized an amylose-grafted poly(vinyl alcohol) (PVA) (4) by a chemoenzymatic method. First, synthesis of an amine-functionalized PVA ... Y Kaneko,SI Matsuda,JI Kadokawa - 《Polymer Chemistry》 被引量: 44发...
free amine (or the hydrochloride salt if hydrochloric acid is used in the hydrogenolysis), though this material needs to be dry and free of alcohol for the subsequent coupling reaction to proceed in good yield. The amine (Formula 3) so obtained is then condensed with the pyrimidine carboxylic...
organic solvent such as a lower aliphatic alcohol (such as ethanol), benzyl alcohol, acetonitrile, nitromethane or glycol ether, at a temperature between -20° C. and the boiling point of the reaction mixture in the presence of a base such as an alkali metal hydroxide or an organic amine....
(1996): Converting an alcohol to an amine in a cationic lipid dramatically alters the co- lipid requirement, cellular transfection activity and the ultrastructure of DNA cytofectin complexes. Biochimica et Biophysica Acta 1280, 1-11Wheeler CJ,Sukhu L,Yang G,et al.Converting an alcohol to an ...
In the last step nicotineamine adenine dinucleotide was consumed in reduced form (NADH), which was monitored spectrophotometrically via determination of the decrease in absorption at 340 nm. Typically a total volume of 3 ml was applied, containing 2878.5 μM of a 50 mM triethanolamine buffer ...
Organic bases such as the amines may also be 1·~·^1I- i i:iLI-Y1~_--i~~ used a4 the basic reagent although the speed of the reaction with them is usually much less than when using the alkali alcoholates and the yield not as high. Amine bases such as triethylamine and tributylami...
