Dynamic asymmetric induction (DYASIN) of racemic dynamic chiral heterohelicenes afforded their highly enantioenriched forms (up to 96% ep) in quantitative yields. These heterohelicenes were readily converted into semi-static axial-chiral 1,1′-binaphthyl derivatives in a stereospecific manner.
外消旋动态手性异螺旋烯的动态不对称诱导 (DYASIN) 以定量产率提供了它们高度对映体富集的形式(高达 96% ep)。这些异螺旋烯很容易以立体定向的方式转化为半静态轴向手性 1,1'-联萘衍生物。
