Functionalized free radical addition/cyclization reactions represent an efficient way for introducing new functionality or coupling fragments to molecules. Ynones are good regional selectivity radical acceptors in organic synthesis, and many of bio-relevant cyclic compounds could be easily obtained by direct radical cyclization reaction. Here, we report a photocatalytic cascade radical addition of
官能化自由基加成/环化反应代表了向分子引入新官能团或偶联片段的有效方法。炔酮是有机合成中良好的区域选择性自由基受体,许多生物相关的环状化合物可以通过直接自由基环化反应轻松获得。在这里,我们报道了联芳基炔酮的光催化级联自由基加成,用于特殊碳循环的发散合成。此外,将多官能团产物进一步转化为各种其他衍生物,证明了这种开发方法的合成价值。
