A convenient synthesis of several 6-heterocyclically appended tri- O -methyl 6-desmethyl emodin derivatives including the tetrazolyl, oxazolyl, oxazolinyl, benzimidazolyl, benzoxazolyl, and benzothiazolyl derivatives of potential biological and medicinal interest was achieved starting from the tri- O -methyl protected emodin aldehyde or nitrile. In addition, these derivatives could serve as synthons
