Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Article，once mentioned of 10343-06-3, Formula: C14H20O10
Methyl (2E,4E?)-5-(2?,3?,4?,6?-tetra-O-acetyl-p-D- glucopyranosyloxy)penta-2,4-dienoate 16a, assembled by a Wittig condensation of tributyl(methoxycarbonylmethylene)phosphorane 19a and (2E)-3-(2?,3?,4?,6?-tetra-O-acetyl-?- Dglucopyranosyloxy)propenal 20, displays excellent Re-face reactivity towards diethyl azodicarboxylate 15a, bis(2,2,2trichloroethyl) azodicarboxylate 15b, dibenzyl azodicarboxylate 15c, diisopropyl azodicarboxylate 15d and di-tertbutyl azodicarboxylate 15e in thermal hetero-Diels-Alder reactions to give the cycloadducts 17a-e. When subjected to the action of hydrogen over palladium-carbon, the cycloadducts 17a, 17b, 17d and 17e undergo hydrogenation of their olefinic bonds to give the dihydro derivatives 18a, 18b, 18d and 18e; in the case of the cycloadduct 17c, hydrogenolysis of the benzyloxycarbonyl group also occurs to give methyl (35)-2,3,4,5-tetrahydropyridazine-3carboxylate Ib with an ee of 98% and 2,3,4,6-tetra-O-acetyl-?-D-glucopyranose 22. Compound Ib, with an ee of 98%, is also available from the dihydro derivative 18e by the action of trifluoroacetic acid; however, under the acidic conditions, a condensation reaction between the aglycone Ib and the glycone 22 competes to give methyl (35)-2,3,4,5tetrahydro-2-(2?,3?,4?,6?-tetra-0-acetyl- ?-D-glucopyranosyl)pyridazine-3-carboxylate25. Sodium (35)-2,3,4,5-tetrahydropyridazine-3-carboxylate le, with an ee of 99%, is available from the ester Ib by a saponification reaction. The trifluoroacetic acid salt 27, with an ee of 95%, is obtained from benzyl (35,6S)1,2-bis(tert-butoxycarbonyl)-1,2,3,6-tetrahydro-6-(2?,3?, 4?,6?-tetra-O-acetyl-beta-D-glucopyranosyIoxy)pyridazine-3- carboxylate 17g by a hydrogenation-trifluoroacetolysis sequence. A hetero-Diels-Alder reaction involving the benzyl pentadienoate 16c and di-tert-butyl azodicarboxylate 15e provides the cycloadduct 17g. The Royal Society of Chemistry 1999.
