Synthesis of 4-Acetoxyindolesand Related Derivatives by Means of Air Oxidation of 4-Oxo-4,5,6,7-tetrahydroindolesObtained from Nitroalkenes and Cyclohexane-1,3-diones

A novel method for synthesizing 4-hydroxyindole derivatives fromcyclohexane-1,3-diones and nitroalkenes have been developed in whicha newly developed air oxidation of 4-oxo-4,5,6,7-tetrahydroindolesis playing a crucial role.
