嗪草酮上游产品

嗪草酮下游产品

3,3-二甲基丁酸-2-酮的制备以3，3-二甲基丁酮-2为原料，经氯化、水解（重排）、氧化、中和4步反应制得。

硫代卡巴肼的制备以水合肼和二硫化碳为原料，按一定配比进行加成和脱硫化氢反应，制得硫代卡巴肼，收率85%～90%。
嗪草酮的合成将上述合成的3，3-二甲基丁酸-2-酮与硫代卡巴肼，在催化剂存在下，进行环合反应，得4-氨基-6-特丁基-3-巯基-1，2，4-三嗪-5-（4H）-酮；此酮式与烯醇式在一定条件下存在动态平衡，加碱使酮式转化烯醇式；再与溴甲烷反应得嗪草酮。
嗪草酮的合成也可将硫代羰基肼盐酸盐溶解在二甲亚砚中，与2-特丁基氨基-3，3-二甲基丁腈反应1h，冷却至20℃，注入冰水，搅拌1h，乙醇重结晶，得3-硫基-4-氨基-5-亚氨基-6-特丁基-1，2，4-三嗪（m.p.181℃)。将其与乙醇、酸在100℃反应2h，冷却至20℃，分离结晶物，过滤，干燥，得3-硫基-4-氨基-6-特丁基-1，2，4-三嗪-5-酮（m.p.215～217℃)。最后在氢氧化钠和甲醇的混合物中，于0℃加磺甲烷，在20℃搅拌反应4h，产物经结晶、过滤、干燥得嗪草酮。

可将硫代羰基肼盐酸盐溶解在二甲亚砜中，与2-特丁基氨基-3,3-二甲基丁腈反应，冷却、搅拌、重结晶得3-硫基-4-氨基-5-亚氨基-6-特丁基1,2,4-三嗪。将其与乙醇、酸反应，分离结晶物，过滤、干燥，得3-硫基-4-氨基-6-特丁基1,2,4-三嗪-5-酮。最后在氢氧化钠和甲醇的混合物中，加碘甲烷反应，产物经结晶、过滤、干燥得嗪草酮。
