Research speed reading in 2021. Reference of 1745-07-9, Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings. 1745-07-9, Name is 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, molecular formula is C11H15NO2. In a Article，once mentioned of 1745-07-9

In the search for potential psychotropic agents, a new series of 3,7-dimethyl- and 1,3-dimethyl-8-alkoxypurine-2,6-dione derivatives of arylpiperazines, perhydroisoquinolines, or tetrahydroisoquinolines with flexible alkylene spacers (5?16 and 21?32) were synthesized and evaluated for 5-HT1A/5-HT7 receptor affinities as well as PDE4B1 and PDE10A inhibitory properties. The 1-(4-(4-(2-hydroxyphenyl)piperazin-1-yl)butyl)-3,7-dimethyl-8-propoxypurine-2,6-dione (16) and 7-(2-hydroxyphenyl)piperazinylalkyl-1,3-dimethyl-8-ethoxypurine-2,6-diones (31 and 32) as potent dual 5-HT1A/5-HT7 receptor ligands with antagonistic activity produced an antidepressant-like effect in the forced swim test in mice. This effect was similar to that produced by citalopram. All the tested compounds were stronger phosphodiesterase isoenzyme inhibitors than theophylline and theobromine. The most potent compounds, 15 and 16, were characterized by 51 and 52% inhibition, respectively, of PDE4B1 activity at a concentration of 10?5 M. Concerning the above findings, it may be assumed that the inhibition of PDE4B1 may impact on the signal strength and specificity resulting from antagonism toward the 5-HT1 and 5-HT7 receptors, especially in the case of compounds 15 and 16. This dual receptor and enzyme binding mode was analyzed and explained via molecular modeling studies.

The chemoselective hydrogenation of carboxylic acids to either alcohols or alkanes is reported, employing a heterogeneous bimetallic catalyst consisting of rhenium and palladium supported on graphite. alpha-Chiral carboxylic acids were hydrogenated without loss of optical purity. The catalyst displays a reverse order of reactivity upon hydrogenation of different carboxylic functions with esters being less reactive than amides and carboxylic acids. This allows for chemoselective hydrogenation of an acid in the presence of an ester or an amide function.

A metal-free oxidative cross-dehydrogenative coupling of N-aryl tetrahydroisoquinolines and 2-methylazaarenes in water under mild conditions has been developed. 4-Acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate was employed as a mild oxidant that can be recovered and reused directly. The reaction proceeds through formation of an iminium ion in situ followed by condensation with various nucleophiles, providing the desired products in moderate to good yields.

Treatment of 2-methyl-1,2,3,4-tetrahydroisoquinoline (1) with 1-2 molar equivalents of triphenylcarbenium tetrafluoroborate at 20C in either chloroform or acetonitrile resulted in the formation of 2-methyl-3,4-dihydroisoquinolinium tetrafluoroborate (2), whereas triethylamine and N-methylpiperidine were unaffected under these reaction conditions. This hydride abstraction was exploited in a one-pot preparation of 1-functionalized 2-alkyl-1,2,3,4-tetrahydroisoquinolines. Thus, treatment of 2 with aqueous potassium hydroxide afforded 1-hydroxy-2-methyl-1,2,3,4-tetrahydroisoquinoline (9) (61% from 1). Similarly, potassium cyanide in acetonitrile provided 1-cyano-2-methyl-1,2,3,4-tetrahydroisoquinoline (10, 77%). Quenching of 2 with Grignard reagents in tetrahydrofuran afforded the corresponding 1-alkyl and 1-aryl substituted tetrahydroisoquinolines (31 to 78%). Interestingly, nitrile 10 reacted very rapidly (<2 min at 0C) with phenylmagnesium bromide to give 2-methyl-1-phenyl-1,2,3,4-tetrahydroisoquinoline (3, 100%), but failed to react with excess phenyllithium even at 20C.
