Tylophorinine, the minor alkaloid of Tylophora asthmatica, has been oxidized to yield 2,3,6-trimethoxyphenanthrene-9,10-dicarboxylic acid. A synthesis of the corresponding imide has been achieved. Desoxytylophorinine, obtained by hydrogenolysis of the alkaloid, has been synthesized. These results in conjunction with other degradation experiments have enabled the assignment of the structure XIV to tylophorinine
tylophorinine,哮喘的Tylophora哮喘的次要生物碱,已被氧化生成2,3,6-三甲氧基菲-9,10-二羧酸。已经实现了相应酰亚胺的合成。已经合成了通过生物碱的氢解获得的脱氧酪氨酸。这些结果与其他降解实验相结合,已使结构XIV可归属于酪氨酸。
