Organocerium compounds (RLi-CeCl3) are able to transfer an alkyl group to the carbonylic function of a β-hydroxyketone giving alkyl substituted 1,3-diols in excellent yields. The use of these not sophisticated reagents is essential to depress undesired dimetallation and retroaldol side processes.

Homoallylicalcohols are oxidized to β-hydroxy ketones using a TBHP-mediated Pd-catalyzed Wacker-type oxidation. The use of a bidentate ligand, quinoline-2-oxazoline (Quinox), and TBHP(aq) as the terminal oxidant provides good yields of the desired products with reaction times significantly reduced as compared to the Tsuji−Wacker oxidation. Additionally, bis- and tris-homoallylic alcohols are oxidized
