Asymmetric hydrogenation reactions of quinolines and 3,4- dihydroisoquinolines using the chiral cationic ruthenium complex Ru(TsDPEN) [TsDPEN=N-(p-toluenesulfonyl)-1,2-diphenylethylenediamine] as catalyst in neat imidazolium ionic liquids have been investigated. The catalytic performance was influenced by the anion of the ionic liquids for both substrate classes. A range of 2-alkyl-substituted 1,2,3,4-tetrahydroquinolines and 1-alkyl-substituted 1,2,3,4-tetrahydroisoquinolines was obtained in high yields with up to >99% ee. Interestingly, the hydrogenation of quinoline derivatives bearing a carbonyl group was selective for the C-N (quinoline) over the C-O (ketone) bonds, while such a unique chemoselectivity was not observed in methanol. Furthermore, the ruthenium catalysts could be easily recycled at least 5 times in the asymmetric hydrogenation of 3,4-dihydroisoquinoline by solvent extraction. To further facilitate the recovery of catalyst and reduce the use of organic solvent, a thin film of ionic liquid containing Ru(TsDPEN) was supported on silica gels. This supported ionic liquid-phase catalyst was effective in the asymmetric hydrogenation of quinoline, and could be recycled at least 6 times by simple filtration. Copyright

Multivariate Curve Resolution with Alternating Least Squares (MCR-ALS) has been successfully applied to in situ infrared measurements of rhodium catalysed asymmetric transfer hydrogenation (CATHy) reaction of 1-methyl-6,7-dimethoxy-3, 4-dihydroisoquinoline to provide an alternative to the traditional method of HPLC analysis. The pure spectra and concentration profile of the imine, amine and carbon dioxide (an intermediate component) were resolved without previous calibration information regarding the reaction. The root mean square prediction error (RMSPE) of the imine and amine were 0.02 and 0.04, respectively. The FTIR method developed enabled the reaction to be monitored in situ, which eliminated the need for constant sampling, required of HPLC analysis, and facilitated the quantitation of components not identified in the chromatographic analysis (CO2).

4721-98-6, Name is 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinoline, belongs to isoquinoline compound, is a common compound. Recommanded Product: 6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinolineIn an article, once mentioned the new application about 4721-98-6.

The reaction of the anion of 3-methoxyphthalide with 3,4-dihydroisoquinolines affords 13-spiro-substituted protoberberines rather than the expected 8,13-dioxo derivatives. Whilst the parent 3,4-dihydroisoquinoline reacts stereospecifically to yield the (13S*,13aS*) diastereomer, the 1-methyl derivative affords exclusively the (13R*,13aS*) isomer. This change in stereochemical outcome is attributed to conformational changes induced by the methyl group in the putative 8,13-dioxo-intermediates.
