Ab. Bueno et al., STEREOSELECTIVITY IN THE ADDITION OF ALUM INUM AND MAGNESIUM REAGENTSTO ((S)R)-2-P-TOLYLSULFINYLCYCLOHEXANONES, Anales de quimica, 90(7-8), 1994, pp. 442-451
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.
