Ozonolysis and reduction of olefinic derivatives of ricinolic acid and L-menthol were studied using hydroxylamine hydrochloride and sodium trisacetoxyborohydride to reduce the peroxide products.

Hydroxylamine hydrochloride efficiently reduces peroxide products of olefins ozonolysis into carbonyl compounds. Depending on the substrate character, solvent, and the treatment conditions the arising aldehydes transformed along the route aldehyde -> aldoxime -> nitrile -> ester into individual compounds or their mixtures, or give the corresponding acetals.

The regioselectivily in the hydroboration-oxidation of ricinoleic acid derivatives only slightly depends oil the configuration of the optically active center: the fraction of the resulting 1,3-diol is larger by 6-10% than that of the 1.4-isomer. The new asymmetric center has preterentially S configuration, as follows from the formation of the corresponding stereoisomeric 1.3-dioxane from the 1,3-diol and of 2,5-dialkyltetrahydrofuran from the 1,4-diol.
