Palladium-catalyzed cross-coupling of isoalantolactone with 1,3-disubstituted or 1-substituted 5-bromo(iodo)uracils afforded mainly (13E)-13-(2,4-dioxotetrahydropyrimidin-5-yl)eudesma-4(15),11(13)-dien-8β,12-olides whose yields depended on the composition of the catalytic system, base, and additive. The structure of (13E)-13-[3-(2-cyanoethyl)-2,4-dioxotetrahydropyrimidin-5-yl]eudesma-4(15),11(13)-dien-8β,12-olide was proved by X-ray analysis. 相似文献

The eudesmane-type methylene lactones (isoalantolactone, alantolactone, 4,15-epoxyisoalantolactone, 2′,2′-dichloro-4H-spiro[cyclopropane-1′,4-eudesma-11(13)-en-8β,12-olide], and alantolactone) react with 8-bromoxanthines (8-bromocaffeine, 8-bromotheobromine, 8-bromo-3-butyltheobromine, 8-bromotheophylline, 8-bromo-9-butyltheophylline) under Heck reaction conditions to produce the target (E)-13-(2,6-dioxo-2,3-dihydro-1H-purin-8-yl)eudesma-4(15),11(13)-dien-8β,12-olides and the subsequent endocyclic isomers - 11-(2,6-dioxo-2,3-dihydro-1H-purin-8-yl)-13-normethyleudecma-4(15)-7(11)-dien-8α,12-olides. It was revealed that the yield and product ratio depends on the reaction conditions and the structure of methylene lactone. The effectiveness of Pd(OAc)2–caffeine catalytic system has been demonstrated in this reaction. The electric eel acetylcholinesterase inhibitory activity of the eudecmanolide-xanthine hybrids was evaluated. Among the new type bisheterocycles compound 27 with butyl and 2-oxodecahydronaphtho[2,3-b]furan-3(2H)-ylidene)methyl substituents at C-7 and C-8 of the xanthine core showed moderate activity with IC50 value of 40 μM. 相似文献

A method for preparing a multicapillary column with a porous layer based on the styrene-divinylbenzene copolymer has been
developed. The column makes it possible to quickly separate C1–C4 hydrocarbons and oxygen-containing compounds. The main chromatographic properties of the columns were studied. 相似文献
