N-formylated thioxopyrimidines 3a-d, thiazine derivatives 4a–c and N-formylated oxopyrimidines 5a–d were synthesized by reaction of an appropriate ethyl 6-methyl-4-aryl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate with DMF in the presence of POCl3 under different conditions. Furtherer reaction of the thiazine derivatives 4a–c with aqueous HCl under heating followed by neutralization with NaOH gave 7a–c
通过适当的乙基 6-甲基-4-芳基-2-硫代-1,2 的反应合成了三个不同系列的化合物,包括 N-甲酰化的 thioxopyrimidines 3a-d、噻嗪衍生物 4a-c 和 N-甲酰化的 oxopyrimidines 5a-d ,3,4-tetrahydropyrimidine-5-carboxylate 与 DMF 在 POCl3 存在下在不同条件下。噻嗪衍生物 4a-c 在加热下与 HCl 水溶液进一步反应,然后用 NaOH 中和得到 7a-c。红外和核磁共振光谱以及元素分析用于鉴定新化合物。
