Abstract
A free radical reaction between 2-aryloxy-1,4-naphthoquinones and dialkly m alonates initiated by manganese(III) acetate is described. This reaction pr ovides a new method for the synthesis of 6,11-dihydro-6,11-dioxobenzo[b]xan thenes. With meta substituent on aryloxy ring, this reaction shows unusual high regioselectivity.
