摘要:
The reactions of (S2,Rs) and (R2,Rs)-2-p-tolylsulfinylcyclohexanones with AlMe3/ZnCl2 only yield the cyclohexylmethylcarbinols with R configuration at hydroxylic carbon. The (R1,S2,Rs)-1-methyl-2-p-tolylsulfinylcyclopentanol was the only compound obtained in the reaction of Me3Al with both epimeric 2-p-tolylsulfinylcyclopentanones. The d.e. of both reactions are higher than 96%.
