“…Such an approach implies selective protection of one of the two hydroxyls followed by oxidation of the remaining free hydroxyl group. This strategy was applied for the preparation of cryptolide [3] and 22-and 23-oxo derivatives of 28-homocastasterone [10]. In both cases, partial acetylation of 22R,23R-diols was used to distinguish the hydroxyl groups.…”

“…The 22,23-dihydroxylated steroid (205) [88] was used as a starting compound for the preparation of 22-and 23-oxo-BS (Scheme 6.37) [89]. The attempts of the diol (205) selective acylation failed.…”
