Abstract
The results obtained in the reactions of ((S)R)-2-p-tolylsulfinyl cycl ohexanones with several aluminun and magnesium reagents reported. High diastereoselectivities are observed in the presence of ZnBr2 regardel ess of the metal and the nature of the organic residue added (alkyl, a ryl, vinyl or ethynyl). An efficient 1,3-asymmetric induction process controlled by the sulfoxide gives rise to tertiary alkylcarbinols with a defined configuration of the new stereogenic center.
