摘要 1 引言2硫脲嘧啶在自然界存在于十字花科植物芸苔的种子里,它也能被人工合成。2硫脲嘧啶用在医药方面,可治疗人的甲状腺机能亢进,心绞痛,充血性心脏衰竭等。此外,有报道说2硫脲嘧啶对牲畜甲状腺也有抑制作用,可治疗甲状腺机能亢进及肥胖症[1]。以往合成2硫脲嘧啶有两种方... A Ethyl ester of Malonaldate was obtatined in the form of Sodium Malonaldate in good yields at ambient temperate and pressure when Methyl Formate is added to a mixture of an excess of Ethyl acetate with and Sodium Methylate.This median substance (Sodium Malonaldate),reacted with Thiourea to give 2 Thiouracil.
