    • The recrystallization procedure in toluene given in ref 10 is not easily reproducible as it is difficult to work under exactly the same experimental conditions. Thus, the recrystallization leads to the precipitation of the two diastereomers in various ratios. However, the less soluble diastereomer, identified as compound 1a (ref 10, can be easily recovered by warming the resulting solid in hot toluene. Filtration followed by recrystallization in a mixture of CHCl3/ethanol affords pure 1a (25, Evaporation of the filtrate, followed by hydrolysis under basic condition, gives rise to enantioenriched, )-cryptophanol 2, which can be used for subsequent reaction with, )-camphanic acid chloride. A similar treatment performed with this diastereomer gives rise to optically pure diastereomer 1b in similar yield
    • 3/ethanol affords pure 1a (25%). Evaporation of the filtrate, followed by hydrolysis under basic condition, gives rise to enantioenriched (+)-cryptophanol 2, which can be used for subsequent reaction with (+)-camphanic acid chloride. A similar treatment performed with this diastereomer gives rise to optically pure diastereomer 1b in similar yield.
