    • For example, use of the acetate derivative of 8c (e.g., i) as a donor in the reaction with cholesterol gave non-reproducible results. In several experiments, the β-glucoside ii was obtained with selectivity of 3-6 : 1, however in one case the α-mannoside iii predominated (4 : 1 selectivity). This reflects the dependence of these glycosidations on subtle variations in reaction conditions. (equation presented) i several runs: 3-6 : 1 selectivity ii R = cholesteryl iii one run: 1 : 4 selectivity
