The preparative conversion of (1R,1′R)-3-exo, 3′-exo-bicamphor (1) in different useful 3-exo, 3′-exo-bibornane derivatives has been explored. The reactivity of bibornane type molecules was controlled by steric factors which made those products recalcitrant towards functionalisation and led to unusual behaviour. Nevertheless the synthesis of the monophosphine alcohol 9 was achieved in 4 steps and in 25% overall yield after a methylenation hydroboration-oxidation methodology applied to (1R,1′R)-3-exo, 3′-exo-bicamphor (1).
