AB  - Expoxidation of cholesta-5,8-dien-3β-yl acetate (1) with peracids takes place preferentially at the more highly substituted Δ8-olefinic double bond to give: (a) with monoperphthalic acid, 8α,9α-epoxycholest-5-en-3β-yl acetate (2) (in 39 % yield) and 9α-hydroxy-5α,6α-epoxycholest-8(14)-en-3β-yl acetate (3) (in 30 % yield); and (b) with m-chloroperbenzoic acid, the 8α,9α-epoxide 2 (64 %) and 5α,6α-epoxy derivative 3 (20 %). Some chemical transformations of the obtained epoxides are described.
AB  - Epoksidacija holesta-5,8-dien-3β-il acetata (1) sa perkiselinama prvenstveno se odvija na više supstituisanoj Δ8-olefinskoj dvoguboj vezi pri čemu se dobija: (a) sa monoperftalnom kiselinom, 8α,9α-epoksiholest-5-en-3β-il acetat (2) (u prenosu od 39 %) i 9α-hidroksi-5α,6α-epoksiholest-8(14)-en-3β-il acetat (3) (u prenosu od 30 %); i (b) sa m-hlorperbenzoevom kiselinom, 8α,9α-epoksid 2 (u prenosu od 64 %) i 5α,6α-epoksi derivat 3 (u prenosu od 20 %). Opisane su i neke hemijske transformacije dobijenih epoksida.

AB  - Treatment of steroidal isoxazolidines 3a, 3b and 5b with N-methylhydroxylamine hydrochloride in boiling ethanol-pyridine (1:1) solution results in elimination of the CH3NH2fragment, affording products of oxidative hydrolysis 4a, 4b, and 6b, while acid-catalyzed reaction of isoxazolidines 2a, 3a and 5b leads to rearrangement involving the N-CH3 group with formation of the perhydro-3,1-oxazine derivatives 8a, 9a and 10b.
