Attempted synthesis of chiral substituted fulvenes

Treatment of benzoin with cyclopentadiene in NaOH/MEOH and pyrrolidine/ MEOH gave benzil via an Oppenauer oxidation, rather than the desired 6-phenyl-6-phenylmethanolfulvene. Treatment of (+)-(lS)-10- camphorsulfonamide and (-)-camphorsulfonimine with cyclopentadiene in NaOH/MEOH and pyrrolidine/ MEOH led to an equilibrium mixture of 10- camphorsulfonamide and (-)-camphorsulfonimine, rather than the desired Camphorsulfonamidefulvene. Treatment of (+)-(! R)-camphor with cyclopentadiene and pyrrolidine/MEOH resulted in a high yield recovery of the starting material and none of the desired camphorfulvene
