Synthesis of a novel recoverable and reusable TentaGel-OsO_4 catalyst is described. The resulting osmylated resin is air-stable and much easier to handle than its homogeneous counterpart (OSO_4). Moreover, the resin-bound Oso_4 exhibited excellent catalytic activity in the asymmetric dihydroxylation of olefins and was easily recovered and reused in five consecutive reactions, without significant decrease in activity.
