by SnCl 2 .2H 2 O affords eight different substituted 3,4-dihydropyrimidine ones/ thiones. Further we prepared acetylated 3,4-dihydropyrimidine ones/thiones, on treatment of 3,4-dihydropyrimidine ones/thiones with acetic anhydride using zinc chloride as a catalyst. Calcium channel blocker activity shows that synthesized compounds have moderate activity.
通过SnCl 2 .2H 2 O将乙酰乙酸乙酯与各种对位和邻位取代的醛以及脲或硫脲进行一锅缩合,得到八种不同的3,4-二氢嘧啶基/硫酮。进一步,在使用氯化锌作为催化剂,用乙酸酐处理3,4-二氢嘧啶基/硫酮的过程中,我们制备了乙酰化的3,4-二氢嘧啶基/硫酮。钙通道阻滞剂活性表明合成的化合物具有中等活性。
