3-PRENYLINDOLES FROM MURRAYA PANICULATA AND THEIR BIOGENETIC SIGNIFICANCE

Article abstract of DOI:10.1016/0031-9422(89)85027-7

Three new 3-prenylindoles named paniculidines A, B and C were isolated from the root bark of Murraya paniculata together with the known coumarins murralongin and osthol.Their stuctures were elucidated as methyl 2-(R)-methyl-4-(3-indolyl)-butyrate, 2-(R)-methyl-4-(1-methoxy-3-indolyl)-1-butanol and 2-(R)-methyl-4-(3-indolyl)-1-butanol, respectively, based on the spectroscopic and chemical evidence.The chemotaxonomic and biogenetic aspects of 3-prenylindole in Murraya has been discussed in conjunction with carbazole biogenesis.Key Word Index - Murraya paniculata; Rutaceae; 3-prenylindole; 1-methoxyindole; coumarin; chemotaxonomy; biogenesis.
