Regiospecific synthesis of title compounds is based either on cycloaddition of ketene acetals derived from Hagemann's ester or of homophthalic anhydrides. Thus, tetracenomycin D and 3,8-di-O-methyl saintopin have been prepared in few steps. New derivatives of 10-deoxysaintopin have been also obtained. Evaluation of their cytotoxicity against L1210 leukemia cells are reported.
标题化合物的区域特异性合成基于衍生自Hagemann酯的酮烯缩醛或高邻苯二甲酸酐的环加成。因此,已经在几个步骤中制备了土霉素霉素D和3,8-二-O-甲基信天翁。还已经获得了10-脱氧赛恩素的新衍生物。报道了其对L1210白血病细胞的细胞毒性评估。
