Camalexin (3-thiazol-2'-yl-indole) is the major phytoalexin found in Arabidopsis thaliana. Several key intermediates and corresponding enzymes have been identified in camalexin biosynthesis through mutant screening and biochemical experiments. Camalexin is formed when indole-3-acetonitrile (IAN) is catalyzed by the cytochrome P450

The chemical structures and accumulation kinetics of several major soluble as well as wall-bound, alkali-hydrolyzable compounds induced upon infection of Arabidopsis thaliana leaves with Pseudomonas syringae pathovar tomato were established. All identified accumulating products were structurally related to tryptophan. Most

A variety of N-alkylated and N-arylated derivatives of methyl 1 H-indole-3-carboxylate were synthesized efficiently via Ullmann-type intramolecular arylamination, using the CuI-K 3PO 4-DMF system. This catalytic amination procedure can be performed with good to high yields under mild conditions under
