Abstract

A free radical reaction between 2-phenylthio-1,4-naphothoquinines and diethyl malonate initiated by manganese(III) acetate is described. This free radical reaction provides a new method for the synthesis of 6,11-dihydro-6,11-dioxo-12H-5-thianaphthacenes. This reaction was performed in various solvents, the best results were obtained in DMSO. With meta substituent on phenylthio ring, this reaction shows unusual high regioselectivity.
