5-(1,2-Diarylethyl)- and 5-(1-aryl-3-butenyl)-barbituric acids are prepared in good yields from, 5-benzylidenebarbituric acids and benzylzinc bromide or allylzinc bromide, respectively. The products are used as starting materials for the synthesis of the correspondingly 5-substituted 1,3,5-triallyl-, 1,3,5-tris [2-propynyl]-, and 5-hydroxybarbituric acid derivatives.
5-(1,2-二叔丁基)-和 5-(1-芳基-3-丁烯基)-巴比妥酸分别由 5-亚苄基巴比妥酸和苄基溴化锌或烯丙基溴化锌以良好的收率制备而成。 这些产物可用作合成相应的 5 取代 1,3,5-三烯丙基、1,3,5-三[2-丙炔基]和 5-羟基巴比妥酸衍生物的起始原料。
