The diastereoselective asymmetric synthesis of vicinal all‐carbon‐atom quaternary stereocenters is a challenging problem in organic synthesis for which only few solutions have been described. A catalytic asymmetric Nazarov cyclization of fully substituted dienones that provides cyclopentenone derivatives with vicinal quaternary stereocenters in high optical purity and as single diastereoisomers is
邻位全碳原子四元立体中心的非对映选择性不对称合成是有机合成中一个具有挑战性的问题,对此仅描述了很少的解决方案。现在报道了完全取代的二烯酮的催化不对称纳扎罗夫环化,其提供具有高光学纯度并且作为单一非对映异构体的具有邻位季铵立体中心的环戊烯酮衍生物。
