To meet the need for a rapid, streamlined, and potentially automatable molecule synthesis, modular coupling approaches are highly desired. While the diversification of aromatic molecules, i.e., Csp2 space, has greatly advanced, modular syntheses in the Csp3 space are comparably much less developed. This report explores the potential of alternative functional handles, i.e., alkyl germanes, in this context
为了满足对快速、流线型和潜在自动化分子合成的需求,非常需要模块化耦合方法。虽然芳族分子的多样化,即C sp2空间,已经取得了很大进展,但C sp3空间中的模块合成相对而言发展得少得多。本报告探讨了替代功能手柄的潜力,即烷基锗烷,在这种情况下,它结合了稳定性和可合成性的特征与选择性反应性。我们展示了烷基锗烷 (R-GeEt 3 ) 在光氧化还原条件下(Giese 加成)的化学选择性功能化以及在模块化构建块中的实现,这允许 C 的选择性多样化sp3 -halogen vs C sp3 -Bpin vs C sp3 -GeEt 3个位点。
