The reactivity of 5-carboethoxy-2-thiouracil (1) toward alkylation by different organohalogen compounds under phase-transfer catalysis (PTC) conditions has been investigated to give S-monoalkylated products and/or simultaneous S- and N-dialkylated products. Also, nucleophilic additions of methylmagnesium iodide, hydroxylamine, and hydrazine to 5-carbethoxy-2-thiouracil (1) have been investigated. The
已经研究了 5-carboethoxy-2-thiouracil (1) 在相转移催化 (PTC) 条件下对不同有机卤素化合物的烷基化反应,以得到 S-单烷基化产物和/或同时发生的 S-和 N-二烷基化产物。此外,还研究了甲基碘化镁、羟胺和肼与 5-carbethoxy-2-thiouracil (1) 的亲核加成。所有产品的结构均已通过元素分析和光谱数据确认。
