A Brønstedacid catalyzed, operationally simple, scalable route to several functionalized α-(3-indolyl) ketones has been developed and the long-standing regioisomeric issue has been eliminated by choosing appropriate carbonyls. A readily available and cheap bottle reagent was used as the catalyst. This protocol was also applicable to the synthesis of densely functionalized α-(3-pyrrolyl) ketones. A

their fluorescent properties in the study of their interaction with DNA and other biological targets, as well as with drug delivery vehicles. A new general method for the synthesis of harmane, harmine, and their structuralanalogs by thermolysis of substituted 4-aryl-3-azidopyridines was developed, and their optical properties were studied.

an aza-alkylation/Michael addition cascadereaction developed by Kim and co-workers we have developed divergent cascadereactions leading to either highly substituted 1-hydroxycarbazoles, 3-hydroxycarbazoles or β-carbolines, starting from readily accessible ortho-arylsulfonylaminobenzaldehydes. Olefination of the aldehyde functionality by aldol condensation or Wittig olefination gave reactive enone intermediates

The present invention relates to β-carboline, dihydro-β-carboline and tetrahydro-β-carboline alkaloid derivatives (I) and a method for preparing same and the use in the aspects of preventing and treating plant viruses, fungicides and insecticides. For the meaning of each group in formula (I) see the description. The β-carboline, dihydro-β-carboline and tetrahydro-β-carboline alkaloid derivatives of the present invention show a particularly ourstanding anti-plant virus activity, and also have fungicidal and insecticidal activities.
