Abstract
<p>A facile and selective β-D-glucuronidation of alcohols, such as (−)-menthol, cholestanol, (+)- and (−)-borneols, and 2-adamantanol, using commercially available methyl 1,2,3,4-tetra-O-acetyl-β-D-glucuronate as the glycosyl donor and trimethylsilyl bis(trifluoromethanesulfonyl)imide (Tf2NTMS) (0.5 equivalent) as the activator in 1,4-dioxane at 60 °C gave products in moderate yields. The addition of MS4A increased the β : α ratios of D-glucuronides when cholestanol, (+)-borneol, and 2-adamantanol were used as the acceptor substrate.</p>
