Two New Isoquinoline Alkaloids from the Barks of Cassia fistula and Their Anti-Tobacco Mosaic Virus Activity

Two new isoquinoline alkaloids, fistulaquinolines A and B (1 and 2), were isolated from the barks of Cassia fistula. Their structures were determined by means of HR-ESI-MS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1 and 2 were tested for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that the two compounds showed weak anti-TMV activity with inhibition rates of 18.9 and 22.6%.

In an article, author is Krapcho, AP, once mentioned the application of 21806-61-1, Application In Synthesis of 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.

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.

Strategies and Synthetic Methods Directed Toward the Preparation of Libraries of Substituted Isoquinolines

Strategies for the production of substituted isoquinoline libraries were developed and explored. Routes involving microwave-assisted variants of the Bischler-Napieralski or Pictet-Spengler reaction allowed for cyclization of substituted beta-arylethylamine derivatives. The dihydroisoquinolines and tetrahydroisoquinolines thus generated could then be oxidized to their corresponding isoquinoline analogues. An alternate strategy, however, involving the preparation and activation of isoquinolin-1(2H)-ones is demonstrated to be a more practical, rapid, and efficient route to C1- and C4-substituted isoquinoline libraries.
