The synthesis of ten ortho-fused PAHs bearing boronic pinacol ester groups (BPin) is reported. The products are obtained via modification of Mallory photocyclization in 45-99% yields. Among them are examples of highly strained molecules such as [4]helicene derivatives with BPin substituents in the cavity. The method allows double C-C coupling and tolerates more than one BPin functionality.
本文报道了十种含有硼酸频哪醇酯(BPin)基团的邻并稠合多环芳烃(PAHs)的合成。这些产物是通过 Mallory 光环化反应的修饰得到的,产率为 45-99%。其中包括一些高度应变分子的例子,如腔体内带有 BPin 取代基的[4]螺旋烯衍生物。该方法允许双 C-C 偶联,并能耐受一个以上的 BPin 官能团。
