  摘要：

  描述了一系列包含二氟对氨基苯甲酸酯环的新型基于C2-甲基-N10-烷基喹唑啉的胸苷酸合酶（TS）抑制剂的合成。制备具有2'，3'-，2'，5'-和2'，6'-二氟取代的N10-炔丙基和N10-甲基喹唑啉抗叶酸酯的衍生物。2'，5'-二氟类似物的合成涉及将二氟硝基甲苯氧化为2,5-二氟-4-硝基苯甲酸，然后进行谷氨酸化，还原和烷基化（炔丙基溴或MeI），生成二乙基N-（4- （烷基氨基）-2，5-二氟苯甲酰基）-L-谷氨酸盐。为了合成2'，3'-和2'，6'-二氟化合物，从4-（（叔丁氧羰基）氨基）-2,6-二氟苯甲酸甲酯及其2,3-替代的对应物。用NaH处理，然后用卤代烷引入N10取代基。水解甲酯，并将所得的酸与L-谷氨酸二乙酯缩合。使用CF 3 CO 2 H释放仲胺，并与6-（溴甲基）-3,4-二氢-2-甲基-4-氧代喹唑啉偶联以产生抗叶酸二酯。在每种情况下，用弱碱进行的最终脱保护均完成
