G. Bartoli et al., ORGANO CERIUM REAGENTS IN ORGANIC-CHEMISTRY - GENERAL-METHOD OF SYNTHESIS OF ALKYL SUBSTITUTED 1,3-DIOLS BY RLI-CECL3 ADDITION TO BETA-HYDROXYKETONES, Tetrahedron letters, 37(13), 1996, pp. 2293-2296
Organocerium compounds (RLi-CeCl3) are able to transfer an alkyl group
to the carbonylic function of a beta-hydroxyketone giving alkyl subst
ituted 1,3-diols in excellent yields. The use of these not sophisticat
ed reagents is essential to depress undesired dimetallation and retroa
ldol side processes.
