    • Note
    • A recrystallization yield of 83% requires the original enantiomeric excess to be higher than the reported value of 81% ee. This discrepancy may be explained by a nonhomogeneous distribution of enantiomers in the solid product of 19 + ent- 19 when the sample for ee determination was taken.
