A new general de novo synthesis of pharmaceutically important α-aryl β-perfluoroalkyl ketones has been disclosed. Compared with trifluoromethylation-initiated radical 1,2-aryl migration of α,α-diaryl allylic alcohols, this protocol employs a new strategy of biomimetic carbene catalysis to assemble alkene, aldehyde and perfluoroalkyl reagents, providing access to products with excellent flexibility
已经公开了药学上重要的α-芳基β-全氟烷基酮的新的从头合成。与三氟甲基化引发的α,α-二芳基烯丙基醇的自由基1,2-芳基迁移相比,该方案采用了仿生卡宾催化的新策略来组装烯烃,醛和全氟烷基试剂,从而提供了具有优异芳基柔韧性的产品单元和全氟烷基。该方法还证明了极好的官能团相容性,包括一些格氏试剂灵敏基团。
