The unsaturated phosphonates were utilized as Hauser acceptors successfully for the first time. The products phosphonylated 1,4-dihydroxynaphthalenes were isolated in good yields in short reaction time and were further oxidized to the corresponding 1,4-naphthoquinones in quantitative yields. The reaction provides an efficient and straightforward approach for the synthesis of pharmacologically privileged
不饱和膦酸酯首次成功地用作豪瑟受体。在短的反应时间内以高收率分离出产物膦酰化的1,4-二羟基萘,并以定量收率将其进一步氧化为相应的1,4-萘醌。该反应为合成具有药理学优势的二取代萘-1,4-二醇和石脑油-1,4-二酮提供了一种有效而直接的方法,该萘基在2位带有膦酸酯基,在3位带有各种(杂)芳基。位置。
