Procedures were developed for the heterocyclization of 2-benzoylethynyl-1- hydroxy-and 1-hydroxy-2-(1-oxo-3-phenylpropynyl)anthraquinone. The regioselective preparation of 2-substituted anthra[1,2-b]pyran-4,7,12-triones was demonstrated to be possible und

A method has been developed for the synthesis of 2-alkenylanthrapyran-4,7,12-triones by the addition of piperidine at the triple bond of 2-alkeynoyl-1-hydroxyanthraquinones with subsequent cyclization of the adducts formed on silica gel.
