3-Acylamino-3-(5-fluorouracil-1-yl) propionates (3a, b) and 4-acylamino-4-(5-fluoro-uracil-1-yl) butyrates (3c-e) were synthesized from 3-acylamino-3-carboxypropionates (1a, b) and 4-acylamino-4-carboxybutyrates (1c-e), respectively, via electrochemical oxidation. Catalytic hydrogenolysis of the benzyl esters (3a, c, d) gave the corresponding carboxylic acids (4a', c', d') without cleavage of the geminal diamine moieties.
3-酰氨基-3-(5-氟尿嘧啶-1-基)丙酸酯 (3a, b) 和 4-酰氨基-4-(5-氟尿嘧啶-1-基)丁酸酯 (3c-e) 分别通过电化学氧化从3-酰氨基-3-羧基丙酸酯 (1a, b) 和4-酰氨基-4-羧基丁酸酯 (1c-e) 合成。对苄基酯 (3a, c, d) 的催化氢解反应生成相应的羧酸 (4a', c', d'),而未裂解邻位二胺基团。
