Abstract

The reductive acetylation of some substituted phenoxazin-3-ones including cinnabarinic acid is described, the products being characterized by infra-red spectroscopy. Additional support is provided for the structures assigned to the reduced acetylated derivatives of cinnabarin and its methyl ester. Nitrous acid has general application as an oxidant for the conversion of phenoxazines into phenoxazin-3-ones.
