title: Syntheses of N-vanillyl-nonanamide glycosides using amyloglucosidase from Rhizopus and beta-glucosidase from sweet almond.
abstract: Enzymatic syntheses of N-vanillyl-nonanamide, 1, glycosides with D-glucose, 2, D-galactose, 3, D-mannose, 4, D-ribose, 5, maltose, 6, and lactose, 7, were carried out using amyloglucosidase from Rhizopus and beta-glucosidase from sweet almond. The latter catalysed the syntheses of N-vanillyl-nonanamide glycosides (8-13) and exclusively yielded beta-glycosides with carbohydrates 2, 3, 4, 6 and 7, while amyloglucosidase yielded C1-alpha- and beta-glycosides and 6-O-aryl derivatives (8, 9, 11 and 12).
