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.

Construction of Spiropyrido[2,1-a]isoquinoline via Tandem Reactions of Huisgen’s 1,4-Dipoles with Various Alkene Dipolarophiles

The three-component reaction of isoquinoline, dimethyl acetylenedicarboxylate and arylidene pivaloylacetonitrile in acetonitrile at room temperature afforded pyrido[2,1-a]isoquinolines 1a-1j in good yields and with high diastereoselectivity. When arylidene-substituted 1,3-indanediones, Meldrum acids, and N,N’-dimethylbarbituric acids were employed in the reaction, the novel functionalized spiro[indene-2,1-pyrido[2,1-a]isoquinolines] 2a-2j, spiro[pyrido[2,1-a]isoquinoline-1,5-[1,3]dioxanes] 3a-3h and spiro[pyrido[2,1-a]isoquinoline-1,5-pyrimidines] 4a-4e were also efficiently synthesized in satisfactory yields. The reaction mechanism included domino formation of Huisgen’s 1,4-dipole, Michael addition and cyclization processes.

Synthesis of regioisomeric difluoro- and 8-chloro-9-fluorobenz[g]isoquinoline-5,10-diones and SNAr displacements studies by diamines: bis(aminoalkyl)aminobenz[g]isoquinoline-5,10-diones

Convenient pathways have been developed for the synthesis of 6,7-, 6,8-, 7,9- and 8,9-difluorobenz[g] isoquinoline-5, 10-diones and 8 -chloro-9-fluorobenz[g] isoquinoline-5,10-dione. The crucial step in these synthesis involved the Ni-catalyzed coupling of the difluoro- or chlorofluorobenzylic zinc bromides with ethyl 3-chloroisonicotinate or ethyl 4-chloronicotinate. The reactions of the 6,7- or 8,9-difluoro regioisomers with N,N-dimethylethylenediamine led to quaternary salts which were formed by intramolecular displacements from the initial mono displacement products. These cyclizations could be obviated with the use of 3-dimethylaminopropylamine in the displacements which led to the desired bis(aminoalkyl) amino substitution products. Treatment of 8-chloro-9-fluorobenz [g]isoquinoline-5,10-dione with N,N-dimethylethylenediamine led to the regioselective displacement of fluoride. Treatment of this mono substitution product with excess N,N-dimethylethylenediamine led only to the intramolecular cyclization product which was also obtained by reaction of 8,9-difluorobenz[g] isoquinoline-9,10-dione with N,N-dimethyletfiylenediamine. The 6,8- and 7,9-difluoro analogues on treatment with N,N-dimethylethylenediamine or 3-dimethylaminopropylamine led to the expected bis substitution products.
