Abstract
Catalyzed by Rh(esp) (10 mol%) and (±)-BINAP (20 mol%) in DCE at 80 °C, the cascade assembly between diazobarbiturates and alkylidene pyrazolones proceeded readily and produced spiro-furopyrimidines in 38-96% chemical yields. The chemical structure of the prepared spirofuro-pyrimidines was firmly confirmed by X-ray diffraction analysis.
摘要
在80℃下于1,2-二氯乙烷中，以Rh(esp)（10摩尔%）和（±）-联萘酚磷酸酯（20摩尔%）为催化剂，重氮巴比妥酸盐与亚烷基吡唑啉酮之间的串联组装反应顺利进行，以38 - 96%的化学产率生成了螺环呋喃嘧啶。通过X射线衍射分析确定了所制备的螺环呋喃嘧啶的化学结构。
