Rh-、Co-或Ir-促进的1，6-烯炔在氢硅烷和一氧化碳存在下的环化导致官能化环状化合物的选择性形成。已经使用各种手性膦型配体以获得对映体富集的碳环。不对称过程进行适度的对映体选择性。(C)2004爱思唯尔有限公司保留所有权利。
Rh-, Co- or Ir-promoted cyclization of 1,6-enynes in the presence of a hydrosilane and carbon monoxide leads to the selective formation of functionalized cyclic compounds. Various chiral phosphine type ligands have been used in order to obtain enantiomerically enriched carbocycles. The asymmetric process proceeded with modest enantioselectivities.
