2, 4-Diamino-6-methylpyrimidine (II) was synthesized from acetoacetonitrile (III) and guanidine which was then converted to 5-amino-7-methyloxazolo [4, 5-d] pyrimidin-2(3H)-one(IX). Several nucleoside type compounds were synthesized by the condensation of IX with some halogenoacetyl and halogenobenzoyl sugars in the presence of metal salts as a halogen acceptor. The antitumor activity of the compounds was tested and found to be inactive.
由乙酰乙腈(III)和胍合成2, 4-二氨基-6-甲基嘧啶(II),然后将其转化为5-氨基-7-甲基恶唑并[4, 5-d]嘧啶-2(3H)-酮(IX )。在金属盐作为卤素受体的存在下,通过 IX 与一些卤代乙酰基和卤代苯甲酰糖的缩合合成了几种核苷型化合物。测试了这些化合物的抗肿瘤活性,发现没有活性。
