A new approach to 3,14-dihydroxyhexahelicene: Resolution and attribution of the absolute configuration

3,14-Dihydroxy[6]helicene 4 was prepared, in a good yield, through a “4 + 1” approach involving the Mizoroki–Heck coupling reaction followed by oxidative photodehydrocylisation. Resolution of this racemic helicenediol was performed by HPLC on a chiral stationary phase, providing both enantiomers (−)...
