Two new syntheses of the phytoalexin methyl 1-methoxyindole-3-carboxylate (1) were developed that employ the same key intermediate. Methyl 2-(2-nitrophenyl)acrylate (2) was directly converted into phytoalexin 1 using modified Cadogan–Sundberg indole synthesis conditions with trimethyl phosphite. Acrylate 2 also underwent reductive cyclization with stannous chloride to give methyl 1-hydroxyindole-3-carboxylate...
The Cadogan–Sundberg indole synthesis produces two major products from the treatment of 2-nitrostilbenes with triethyl phosphite, which are the 2-arylindoles and the corresponding 2-aryl-N-ethoxyindoles. We were interested in determining the origin of the oxygen atom in the 2-aryl-N-ethoxyindoles. In this study, we verify that this oxygen atom originates from the nitro group and not from the triethyl...
