Synthesis of benzylisoquinoline derivatives possessing electron-withdrawing substituents on the benzene ring of the isoquinoline skeleton

3,4-Dihydrobenzylisoquinolines and 1,2,3,4-tetrahydrobenzyl-isoquinolines possessing electron withdrawing substituents on the benzene ring of the isoquinoline framework are easily accessible by a synthetic approach that takes advantage of a Sonogashira coupling to build up the C1-C8a bond of the isoquinoline skeleton and a Ti-catalyzed intramolecular hydroamination of an alkyne to close the heterocyclic ring.

In an article, author is Miki, Y, once mentioned the application of 21806-61-1, Name: Prop-1-ene-1,3-sultone, Name is Prop-1-ene-1,3-sultone, molecular formula is C3H4O3S, molecular weight is 120.1271, MDL number is MFCD12405143, category is isoquinoline. Now introduce a scientific discovery about this category.

Hydrodenitrogenation of isoquinoline

To determine the formation and reactivity of addition compounds produced during hydrodenitrogenation (HDN), we investigated the HDN of isoquinoline for a sulfided Ni-Mo/Al(2)O(3) catalyst operated under a hydrogen pressure of 12 MPa (cold charge) in the temperature range 300-375 degrees C. The reaction products were classified into five groups of compounds: 1. hydrogenated derivatives of isoquinoline (tetrahydroisoquinolines, decahydroisoquinolines, and their isomers); 2. nitrogen-containing ring-opened products (1-amino-2-(2-methylphenyl)ethane and 1-amino-1-(2-ethylphenyl)methane); 3. denitrogenated products (1-ethyl-2-methylbenzene, 1-ethyl-2-methylcyclohexane, and their isomers); 4. addition products (hydrocarbons with molecular weights of 238, 244, and 250 and nitrogen-containing compounds with molecular weights of 249, 251, and 257); and 5. cracked products (toluene, ethylbenzene, dimethylbenzenes, and their hydrogenated derivatives). Most of the nitrogen-containing addition compounds appear to be substituted on the nitrogen atom. The HDN of isoquinoline was more than 10 times faster than the HDN of quinoline, whereas the hydrogenation of isoquinoline was difficult compared to the hydrogenation of quinoline. The reaction network for the HDN of isoquinoline is also presented. (C) 1999 Elsevier Science B.V. All rights reserved.
