Asymmetric reduction of 2-fluoro-2-(trifluoromethyl)-3-hydroxy ketones with lithium aluminum hydride or diisobutylaluminum hydride. Highly stereoselective synthesis of 2-fluoro-2-(trifluoromethyl)-1,3-diols
2-fluoro-2-(trifluoromethyl)-3-hydroxy ketones are reduced in a highly 1,2-syn diastereoselective manner with lithiumaluminumhydride or diisobutylaluminum hydride in tetrahydrofuran at −78 °C, affording 1,2-syn-2,3-syn- and 1,2-syn-2,3-anti-2-fluoro-2-(trifluoromethyl)-1,3-diols, respectively, in excellent yields. High 1,2-syn stereoselectivity in the reduction can be ascribed to the presence of the
