| titleOfInvention | Process for producing 2",3",4'-tris-(acetyl)-4",6"-ethylidene-beta-d-glycopyranozides |
| abstract | The invention relates to Tris acetyl-2˝, 3˝, 4'-ethylidene-4˝, 6˝-β-D-glucopyranosides, their preparation and their use for the preparation of ethylidene β-D-glucopyranoside 4'-demethyl epipodophyllotoxin.n n n The compounds of the invention correspond to formula 1 n n n acylation d'un dérivé glycosylé acylation d'une aglycone couplage du dérivé glycosylé acylé et de l'aglycone acylée, en présence d'un acide de Lewis, nl'acylation étant effectuée à l'aide d'un chlorure d'acide, éventuellement identique pour les deux étapes d'acylation, dans lequel le carbone en α de la fonction carbonyle porte au moins un hétéroatome choisi parmi O et S. Their preparation process comprises the following steps: acylation of a glycosyl derivative acylation of an aglycone coupling the acylated glycosyl derivative and the acylated aglycone, in the presence of a Lewis acid, the acylation being carried out using an acid chloride, possibly identical for the two acylation steps, in which the α carbon of the carbonyl function carries at least one heteroatom selected from O and S. |
