报道一类温和碱促进的环外1,3-二羰化合物、芳基重氮四氟硼酸盐和醇的三组分解构官能化反应, 使无张力环体系能直接开环, 以良好收率合成了六种不同骨架的腙化1,n-二酯衍生物(如1,6-、1,7-、1,8-和1,9-二酯)和1,n-酮酯(如1,6-和1,7-酮酯). 其中, 在形成1,n-酮酯的转化中, 该反应展现出优异(E)-选择性. 在整个有机合成过程中, 该方法具有广泛使用的潜力, 因使用了易于获得的具有不同取代形式的底物, 如环外1,3-二羰化合物和芳基重氮四氟硼酸盐, 以及温和反应条件. 对部分化合物的生物活性, 即对人肺癌细胞株MSTO-211H的抑制作用, 进行了初步检测. 结果显示化合物3c3u展现出较为显著的抑制作用.

A mild base-promoted three-component deconstructive functionalization of exocyclic 1,3-dicarbonyls with aryl diazonium tetrafluoroborates in the presence of alcohols is reported, enabling direct ring-opening of unstrained cyclic ring systems to produce six types of skeletally diverse hydrazonylated 1,n-diesters (e.g., 1,6-, 1,7- 1,8-, and 1,9-diesters) and 1,n-ketoesters (e.g., 1,6- and 1,7-ketoesters) with good yields, and the latter demonstrated complete (E)-selectivity. The methodology has the potential to be widely used throughout organic synthesis due to the use of easily accessible substrates with different substitution patterns, such as exocyclic 1,3-carbonyls and aryl diazonium tetrafluoroborates, and mild reaction conditions. Preliminary biological evaluation of some compounds, namely their inhibitory effect on human lung cancer cell MSTO-211H, was conducted. The results showed that compounds 3c and 3w exhibited significant inhibitory effects.
