  Rh的单膦配体控制的酰基氨基环丙烷的区域发散性氢化硅烷化

  摘要：

  已经开发了Rh催化的酰基氨基环丙烷的区域发散性氢化硅烷化。在Rh催化剂的存在下，酰基氨基环丙烷与氢硅烷反应，通过环丙烷环的碳-碳（CC）键断裂，提供开环的氢化硅烷化加合物。可以通过改变单膦配体来切换添加硅烷（直链或支链）的区域选择性。这种C–C键断裂/氢化硅烷化方法适用于硅烷二醇前体的合成。

  Cooperative Photoredox and Cobalt‐catalyzed Acceptorless Dehydrogenative Functionalization of Cyclopropylamides towards Allylic N,O‐Acyl‐acetal Derivatives

  摘要：

  We disclose herein a novel photoredox and cobalt co‐catalyzed ring‐opening/acceptorless dehydrogenative functionalization of mono‐donor cyclopropanes, which providing a sustainable and atom‐economic approach to rapidly assemble a wide range of allylic N,O‐acyl‐acetal derivatives. The optimized conditions accommodate assorted cycloalkylamides and primary, secondary and tertiary alcohols, with applications in late‐stage functionalization of pharmaceutically relevant compounds, stimulating the further utility in medicinal chemistry. Moreover, selective nucleophilic substitutions with various carbon nucleophiles were succeed in a one‐pot fashion, offering a reliable avenue to access some cyclic and acyclic derivatives.

  ring-opened hydrosilylated adducts through carbon–carbon (C–C) bond cleavage of the cyclopropane ring. The regioselectivity of the addition of silanes (linear or branched) can be switched by changing the monophosphine ligand. This C–C bond cleavage/hydrosilylation methodology is applicable to the synthesis of silanediol precursors.
