    Glycosidic juvenogens: Derivatives bearing alpha,beta-unsaturated ester functionalities

  • Original language description

    A series of the protected alkyl glycosides 5a/5b-12a/12b was synthesized from the parent isomeric alcohols (insect juvenile hormone bioanalogs; juvenoids), 4-[4'-(2"-hydroxycyclohexyl)methylphenoxy]-3-methyl-but-2-enoic acid ethyl ester (Ia/1b-4a/4b; racemic structures) and (1a-4a; enantiopure structures). Cadmium carbonate was used as a promoter of this Koenigs-Knorr reaction. and the products were obtained in 82 92% yields. Deprotection of the carbohydrate functionality of 5a/5b-12a/12b was carefully,performed using ethanolysis in the presence of zinc acetate, due to the presence of another ester functionality in the aglycone part of the molecule of protected alkyl glycosides. Resulting alkyl glycosides 13a/13b-20a/20b (diastereoisomeric mixtures) and 13a20a (enantiopure compounds), biochemically activated hormonogenic compounds juvenogens), were obtained in 82-93/() yields. Finally, chiral HPLC separation of the diastereoisoineric mixtures of alkyl glycosides was applied to get suf

    Glykosidické juvenogeny: Deriváty nesoucí alfa,beta-nenasycené esterové funkce

  • Czech description

    Byla připravena skupina chráněných alkyl glykosidů, odvozených od mateřských isomerních alkoholů (bioanalogů hmyzích juvenilních hormonů; juvenoidů) v racemických a v enantiomerně čistých formách. Uhličitan kademnatý byl použit jako promotor Koenigs-Knorrovy reakce. Odstranění chránících skupin bylo provedeno ethanolýzou za přítomnosti octanu zinečnatého. Připravené juvenogeny (racemické i enantiomerně čisté sloučeniny) byly podrobeny detailní analýze pomocí 1H a 13C NMR spektroskopie a rovněž základnímu biologickému testování na plošticích Pyrrhocoris apterus.
