    A Scalable and Expedient Route to 1-Aza[6]helicene Derivatives and Its Subsequent Application to a Chiral-Relay Asymmetric Strategy
    摘要:
    A rapid route to diversely functionalized 1-aza[6]helicenes has been achieved via the development of a copper-mediated cross-coupling reaction, followed by PtCl4-catalyzed cycloisomerization. Not only does this method allow access to these functionally important molecules on gram scale, but this strategy Is also suitable for relaying the axial chirality of a key intermediate to the helicity of the product.

    The enantioselective synthesis of fully benzenoid single and double carbo[6]helicenes has been achieved via the gold‐catalyzed intramolecular hydroarylation. The single crystal of the racemic double carbo[6]helicene consists of unique layer structures like timbers with halving joints in the woodworking. Furthermore, the double carbo[6]helicenes exhibited relatively large CPL activities among chiral
