A synthesis of 8,10-dideazaminopterin, using 2,4-diamino-6-bromomethyl-8-deazapteridine (2) as a key intermediate, is described. Condensation of the triphenylphosphinylide derived from 2 with p-formylbenzoyl-L-glutamate afforded a 9,10-dehydro-8,10-dideazaminopterin ester intermediate 5. Hydrogenation of the olefinic linkage and subsequent hydrolysis of the glutamate ester gave the title compound.
描述了使用2,4-二氨基-6-溴甲基-8-脱氮庚啶(2)作为关键中间体的8,10-二氮杂氨基蝶呤的合成。衍生自2的三苯基次膦酰基与对甲酰基苯甲酰基-L-谷氨酸的缩合,得到9,10-脱氢-8,10-二氨基氮杂蝶呤酯中间体5。烯烃键的氢化和谷氨酸酯的随后水解得到标题化合物。8,10-Dideazaminopterin是一种有效的叶酸依赖性细菌生长抑制剂。作为来自L1210白血病细胞的二氢叶酸还原酶抑制剂,它的效力是甲氨蝶呤的16倍,并且在小鼠中显示出对L1210的强活性。
