The literature review shows that direct transformation of epoxides to 1,2-diacetates has been obtained in the presence of various catalysts/reagents such as HCl/ZnCl2 [3], BF3 Et2O [4], DBU/LiCl [5], n-Bu4NCl [6], n- Bu4NOAc [7], Bu3P [8], LiClO4 [9], Er(OTf)3 [10], HY zeolite [11], (NH4)3PMo12O40 [12], (TBA)4P- FeW11O39 3H2O [13], ZrO(OTf)2 [14], NaBH4 [15], phosphomolybdic acid or its supported on silica gel [16] and molecular sieves 4A [17].
The study results showed that the mean tissue (MD) in the second group on the seventh day was significantly higher than the 1.8 times of the first group; the third group with the implant UP was 1.3 times; in the fourth group of the implant of BF3, sixfold, respectively, indicating the activation of LPO and MD accumulation in tissues.
Next, 2.18 ml BF3 (12%) in methanol was added and the mixture was heated for another 2 min.
All the lipids were transesterified using boron-trifloride methanol (BF3 14% methanol, Supelco, Bellefonte, PA, USA), and analyzed in a Hewllet-Packard CG 6890-N gas chromatography equipped with a DB-23 (30 min length x 0.25 mm inner diameter, 0.25 [micro]m-thick-film) fused silica capillary column (J.
(12) It was a lucky break to find out that BF3 treatment of 3-acetate of fucosterol 24,28-epoxide (FE) (9) yielded desmosterol acetate together with usual epoxide-carbonyl rearrangement products during chemical studies of the fucosterol [[DELTA].sup.24(28)]-double bond.
