Nucleophilic Substitution Reaction of 3-Acetyl-1-methoxyindole and Its Application for the Synthesis of Novel 2-Substituted Methyl 2,3-Dihydro-1-methyl-3-oxo-5H-pyrido[4,3-b]indole-4-carboxylates
A simple synthetic route was established for 3-acetyl-1-methoxyindole, which was found to undergo nucleophilic substitution reactions selectively at the 2-position. Applying the reaction, novel 2-substituted methyl 2,3-dihydro-1-methyl-3-oxo-5H-pyrido[4,3-b]indole-4-carboxylates were prepared.
