Reductive dehydroxylation of Baylis–Hillman adducts with low-valent titanium reagent: syntheses of stereoselective trisubstituted alkenes

The Baylis–Hillman adducts prepared from aromatic aldehydes and methyl acrylate underwent smooth dehydroxylation with concomitant olefin isomerisation with low-valent titanium reagent to provide the trisubstituted alkenes with high (E)-selectivity.
