Abstract

We have validated a novel detagging strategy featuring the unmasking of a fluorous-tagged silane to a hydroxy moiety. The fluorous silylated bicyclononane, prepared from the titanium-mediated annulation of 1-acetylcyclohexene and a fluorous-tagged allylsilane, was successfully detagged under Fleming-type oxidation conditions. The stereochemistry of the resulting hydroxylated product indicates retention of configuration upon detagging in line with the non-fluorous variant of this transformation.
