Abstract

Abstract : The front cover picture illustrates the palladium‐catalyzed the chirality transfer from peripheral stereogenic carbon center to axial chirality starting from 8 H ‐indenothiophen‐8‐ols. The process is different from traditional point‐to‐axial chirality transfer aromatization reaction of a non‐aromatic intermediate, in which the new created chiral axis is usually directly attach to a stereogenic centers. This reaction provides an easy way to access highly functionalized 3‐arylthiophene atropisomers in high enantioselectivity.
