alkenes, which enables the synthesis of chromans, quinolinones, and tetrahydronaphthalenes that are precisely deuterated at the benzylic position. We also demonstrate the ability to place one deuterium atom at the homobenzylic site of these scaffolds with high regioselectivity by swapping transfer reagents for their isotopic analogs. Furthermore, examples of chemoselective transfer hydrogenation and transfer
选择性地将氘安装到小分子中变得越来越可取,这不仅是为了阐明机械途径和研究生物过程,而且还因为氘能够有利地调整生物活性分子的药代动力学参数。稠合双环部分,尤其是那些含有杂原子的部分,在药物发现和制药中很普遍。在此,我们报道了铜催化的环状和杂环烯烃的转移加氢氘化反应,它能够合成在苄基位置精确氘化的苯并二氢吡喃、喹啉酮和四氢萘。我们还展示了通过将转移试剂交换为其同位素类似物,以高区域选择性将一个氘原子放置在这些支架的同型苄基位点的能力。此外,
