In addition to 22, formation of a side product, which was tentatively assigned as hydroxylamine hemiacetal diastereomer 22′, was observed. This mixture was subjected to the next acetonide formation without separation.

note
-
The ratio of 22/22′ was almost the same as that of 23 and a side product, which was tentatively assigned as 23′. Furthermore, deprotection of the acetonide of 23 and 23′ under acidic conditions (HCl (1N) in THF, room temperature) gave only 22 and 22′, respectively. These observations would indicate that neither epimerization of C7 nor interconversion of the hemiacetal diastereomers via the eight-membered ring ketone occurred during the acetonide formation.
