But-3-en-2-yl glycosides have been obtained by glycosidase-catalysed transformations under thermodynamic conditions, and reaction parameters have been optimised. It has been shown that the enzymes can be immobilised on non-ionic Amberlite resin (XAD-4) and can conveniently be retrieved and re-used in a subsequent glycosylation. The enzyme-catalysed reactions display some diastereodifferentiation with a preference for the (R)-over the (S)- ...
