5 days ago · 天然产物scabrolide A和havellockate的发散性合成. 最后，作者对这一高效的自由基串联环化步骤进一步进行了研究，发现该反应拥有非常好的官能团兼容性，无论是将缩醛转化为醚、内酯，还是用不同官能团取代的底物，都能以较好的收率得到相应产物，尤其是环丙烷取代的炔烃也能很好的兼容，而不会发生自由基开环反应。 DFT计算也佐证了这一实验结论。 进一步的计算研究表明，自由基中间体（INT1）的刚性三环骨架是6-endo选择性的关键因素。 图4. 自由基环化反应机理研究. 这一成果近期发表在Journal of American Chemical Society 上。 文章的共同第一作者是西湖大学的博士研究生彭辰、博后郭全平和浙江大学的博士研究生徐国雄。
