Abstract:

Farnesene and its conjugated triene oxidation products in apple peel are positively correlated with, and thought to be involved in, the storage disorder superficial scald. Levels of these compounds are often estimated by dipping fruit in hexane and measuring the absorbance of the crude extracts at 232 nm (farnesene) and 269 or 281 minus 290 nm (trienes). We have devised a C18 HPLC method with UV detection at 232 and 269 nm that allows the simultaneous quantitation of 80 ng of farnesene and trienes. Using this method we have confirmed the recent report that one conjugated trien-6-ol comprises 9

Starting from estrone 3-benzyloxy-17β-hydroxyestra-1,3,5(10)-trien-16-one oxime (3b) was synthesized, which underwent Beckmann fragmentation giving the 3-benzyloxy-17-oxo- 16,17-secoestra-1,3,5(10)-triene-16-nitrile (4b). Sodium borohydride reduction of this compound afforded 3-benzyloxy-17-hydroxy-16,17-secoestra-1,3,5(10)-triene-16-nitrile (5b). The deprotection of the 3-hydroxy group was achieved by action of hydrogen upon derivatives 4b and 5b in presence of Pd/C as a catalyst, yielding 3-hydroxy-17-oxo-16,17-secoestra- 1,3,5(10)-triene-16-nitrile (4a) and 3,17-dihydroxy-16,17-secoestra-1,

Abstract:

Starting from 3-(benzyloxy)-16-(hydroxyimino)-estra-1,3,5(10)-trien-17-one (1) several 17-methyl-16,17-secoestratriene derivatives were synthesized. In the first step of synthesis, hydroxyimino ketone 1 was transformed into 3-(benzyloxy)-16-(hydroxyimino)-17α-methylestra-1,3,5(10)-trien-17β-ol (2), the Beckmann fragmentation of which gave 3-(benzyloxy)-17-methyl-17-oxo-16,17-secoestra-1,3,5(10)-triene-16-nitrile (3a). Reduction of 3a with sodium borohydride yielded (17S)-3-(benzyloxy)-17-hydroxy-17-methyl-16,17-secoestra-1,3,5(10)-triene-16-nitrile (4a), whose configuration at the newly formed

A new octadecatrienoic acid and a new benzyl glycoside, along with a known compound, were isolated from the leaves of Smallanthus sonchifolius. The structures of the two new compounds were elucidated as 13(R)-hydroxy-octadeca-(9E,11E,15Z)-trienoic acid (1) and benzyl alcohol 7-O-α-L-arabinopyranosyl(1″→2′)-β-D-glucopyranoside (2) on the basis of spectroscopic analysis and chemical evidence. The known compound was identified as 13(R)-hydroxy-octadeca-(9Z,11E,15Z)-trienoic acid (3) by comparison of its spectral data with that reported.

The aim of this work was to study the ability of some estrogen 8a-analogues, that have CH 3 -group in the C-3 position, exhibit osteoprotective and cholesterolemic effects. The properties of these analogues was comparisoned with effects of native estradiol and 17a-ethynylestradiol (EE). We showed that compounds 3 ((d,l)-17b-acethoxy-3-methoxy-8a-estra-1,3,5(10)-triene) and 4 ((d,l)-3-methoxy-8a-estra-1,3,5(10)-triene-17-one) had the same osteoprotective and cholesterolemic effects as EE.

Abstract: Starting from estrone 3-benzyloxy-17-hydroxy-16,17-secoestra-1,3,5(10)-triene- 16-nitrile (1) was synthesized in several synthetic steps. This compound was the key intermediate in the syntheses of other 17-substituted-16,17-secoestrone derivatives. Among them 3-hydroxy-17-bromo-16,17-secoestra-1,3,5(10)-triene-16-nitrile (5) is of special interest, because of its antiestrogenic activity, with no estrogenic properties. For this reason an alternative pathway for the synthesis of this compound was sought. The structures of 3-benzyloxy-17-bromo-16,17-secoestra-1,3,5(10)-triene- 16-nitril
