The catalytic enantioselective oxidative hetero-coupling of arenols using a chiral vanadium(v) complex has been developed. The coupling of hydroxycarbazole derivatives with various arenols provided axially chiral biarenols in high chemo-,...

The electrochemical synthesis of hetero [7]helicenes including pyrrole and furan rings has been established. A single electrochemical operation led to an oxidative heterocoupling and dehydrative cyclization sequence to afford oxaza [7]helicenes in 50-86% yields with 45-77% Faradic efficiencies. Their derivatization and chiroptical properties were also investigated.
