note
-
Attempts to directly establish the enantiomeric purity of compounds 7 through 9 failed. Because any obvious enantio-enriching process (e.g., recrystallization) was carefully avoided during the transformations from compound 7 to 10, the optical purity of compound 7 should be as represented by that of compound 10.
