2-Hydroxyhexahelicene has been prepared in good yield and purity via a three-step sequence involving palladium-catalysed Heck coupling and classical oxidative photocyclisation reactions. The two enantiomers of this hexacyclic helicenol have been separated using (S)-(-)-camphanoyl chloride as the chiral resolving agent. (C) 2012 Elsevier Ltd. All rights reserved.
