- Expedient synthesis of 1-hydroxy-4- and 1-hydroxy-6-nitroindoles
-
Reaction of -chloroalkyl ketones with 1,3-dinitrobenzenes provides 2,4-dinitrobenzyl ketones which when reduced with tin(II) chloride form 6-nitro derivatives of 1-hydroxyindoles. An alternative approach is the condensation of 2,4- and 2,6-dinitrotoluenes
