"The first nitration of codeine by using bismuth nitrate pentahydrate under mild reaction conditions is described. The resulting 1-nitrocodeine was reduced to 1-aminocodeine, a key precursor for the synthesis of the azo derivative and several hydrazones. Structures of both 1-nitrocodeine and 1-amino-codeine were unequivocally determined by single-crystal Xray analysis. The reported preliminary synthetic study lays the groundwork for the synthesis of modified codeine derivatives with potential biological activity."@en . "6"^^ . . .
