reduction of ω-substituted alkylphenyl ketones, PhCO(CH2)nY, with lithium tri-l-menthoxyaluminum hydride, the effect of the functionalgroups, Y(NR2, OMe, and SMe) on the stereoselectivity was examined in comparison with that of the alkylgroup. Of the functionalgroups tested, the MeO group is more effective in enhancing the stereoselectivity than the NMe2 or SMe group except in the case of n=1.
