but, instead, the pyrimidine rings were joined via a sulfur bridge to give 9,9′-thiobis(1,2,3,4,7,8-hexahydro-7-melnyl-6H-pyrimido[1,6-a]pyrirnidine-6,8-dione) (3). An identical 9,9′-thiobis- derivative 3 was obtained when reacting thionyl chloride with 1,2,3,4,7,8-hexahydro-7-methyl-6H-pyrimido[1,6-a]pyrimidine-6,8-dione (4). We suppose the sulfoxide- derivative 2 to be the intermediate of both routes:
与亚硫酰氯反应时,6-(3-羟丙基氨基)-3-甲基嘧啶-2,4-二酮(1)没有提供预期的6-(3-氯-丙基氨基)-衍生物,而是嘧啶环被加入了通过硫桥,得到9,9'-硫代双(1,2,3,4,7,8 -六氢-7- melnyl -6- ħ嘧啶并[1,6-一个]嘧啶-6,8- dione)(3)。亚硫酰氯与1,2,3,4,7,8-六氢-7-甲基-6 H-嘧啶并[ 1,6- a ]嘧啶-6反应时,获得相同的9,9'-硫代双衍生物3,8-二酮(4)。我们假设亚砜衍生物2是这两种途径的中间产物:它已还原为最终的硫化物3过量的亚硫酰氯。
