The tandem isomerization-Mannich reaction of octen-3-ol and benzylidene N-sulfonyl imine affords the corresponding β-aminoketones in good yields. Diastereoselective reduction, followed by the deprotection of the primary amine, gives the expected 1-amino-2-methyl-1-phenyloctan-3-ol derivatives in excellent yields and in diastereomerically pure forms.
