5-Chloromethyl-6-ethoxycarbonyluracil (5) was prepared from furo [3, 4-d] pyrimidine-2, 4, 7 (1H, 3H, 5H)-trione (4). Reaction of 5 with some nucleophilic reagents such as secondary amines, alcohols and sodium thiolates afforded 5-(substituted-methyl)-6-ethoxy-carbonyluracils. By treatment of the corresponding esters with methanolic ammonia or ammonia water, 5-(substituted-methyl)-6-carbamoyluracils were prepared. The antitumor activities of the newly synthesized compounds were examined against L-1210 cells in vitro.
5-氯甲基-6-乙氧基羧基尿嘧啶(5)是由呋喃[3, 4-d]嘧啶-2, 4, 7(1H, 3H, 5H)-三酮(4)合成的。5与一些亲核试剂如次级胺、醇类和硫代钠反应,得到了5-(取代甲基)-6-乙氧基羧基尿嘧啶。通过将相应的酯与甲醇氨水或氨水处理,合成了5-(取代甲基)-6-氨基尿嘧啶。新合成化合物的抗肿瘤活性在体外对L-1210细胞进行了评估。
