  The disclosure relates to methods for forming at least partially saturated cyclic and heterocyclic borylated hydrocarbons, as well as related compounds, which can be precursor compounds in the synthesis of any of a variety of pharmaceutical or medicinal compounds with a desired structure and/or stereochemistry for drug synthesis or drug candidate evaluation. The methods generally include reduction of an unsaturated cyclic or heterocyclic borylated hydrocarbon having a boron-containing substituent at an sp 2 -carbon, where such reduction converts the sp 2 -carbon to an sp 3 -carbon at the point of attachment of the boron-containing substituent. The methods can exhibit a selectivity for syn-addition during reduction, which can provide stereospecific products, such as when the unsaturated cyclic or heterocyclic reactant is multiply substituted with boron groups and/or other functional groups.

  本发明涉及用于形成至少部分饱和的环状和杂环硼化烃的方法，以及相关的化合物，这些化合物可以是合成多种具有所需结构和/或立体化学的药物或药用化合物的前体化合物。这些方法通常包括将具有sp2碳上含硼取代基的不饱和环状或杂环硼化烃还原，这样的还原将sp2碳转化为与含硼取代基连接点上的sp3碳。这些方法在还原过程中可表现出对顺式加成的选择性，从而可以提供立体特异性产物，例如当不饱和环状或杂环反应物上多元取代硼基团和/或其他功能基团时。

  We report an enantio- and diastereoselective, complete hydrogenation of multiply substituted benzofurans in a one-pot cascade catalysis. The developed protocol facilitates the controlled installation of up to six new defined stereocenters and produces architecturally complex octahydrobenzofurans, prevalent in many bioactive molecules. A unique match of a chiral homogeneous ruthenium-N-heterocyclic

  我们报道了多取代苯并呋喃在一锅级联催化中的对映和非对映选择性完全氢化。开发的协议有助于受控安装多达六个新定义的立体中心，并产生结构复杂的八氢苯并呋喃，普遍存在于许多生物活性分子中。手性均相钌-N-杂环卡宾络合物和来自络合物前体的原位活化铑催化剂的独特匹配依次作用以实现所提出的过程。
