Acylation of sugar amides over Algerian bentonite and mcm-41 materials

The condensation of sugar with fatty acids in an organic media is possible by chemical amidification without fastidious steps by hydroxyl group protection/deprotection. The acylation of sugar (N-methyl glucamine) with fatty acids (lauric acid, palmitic acid and stearic acid) is catalyzed in the presence of two inorganic and acid solid catalysts: Algerian clay called bentonite of Maghnia and mesoporous material of type (Al–MCM-41). The results obtained with this last solid (i.e. MCM-41) are very encouraging.
