Abstract
A simple synthesis of dimethyl 3,10-dihydro-1,12-dihydroxy-4,5,8,9-tetramethoxy-3,10-dioxoperylene-2,11-dicarboxylate (2), a key intermediate in the synthesis of the Elsinoe pigments, is described, and the unusual mass spectrometric fragmentation of compound (2) and some related compounds, with loss of one oxygen atom, is discussed.Keywords
