Popis: | In this paper we describe a new method for the synthesis of camalexin ( 1 )based on the reaction of 1-(tert-butoxycarbonyl)indole-3-carboxaldehyde with methyl L-cysteinate hydrochloride, followed by oxidation and decarboxylation. Compounds 1 , andintermediates 5 - 7 were identified by elemental analysis, 1 H NMR, 13 C NMR and massspectroscopy. Keywords: Camalexin, phytoalexins, indoles Introduction Camalexin [3-(2 ’ -thiazolyl)indole] ( 1 ) is a natural phytoalexin, isolated for the first time from theleaves of Camelina sativa and elicited by the fungus Alternaria brassicae [1]. Camalexin is also theprincipal phytoalexin found in Arabidopsis thaliana [2]. It exhibits antifungal activity similar to thesystemic fungicide thiabendazole ( 2 ) [1,3] and also has antitumor activity [4]. In the literature there aredescribed four methods for synthesis of camalexin, based on the reaction of indolylmagnesium iodidewith 2-bromothiazole [3], heating of indole-3-carboxamide with P 2 S |
