Özet

A stereospecific synthesis of (2S)-3-(2,4,5-trifluorophenyl)propane-1,2-diol from D-mannitol has been developed. The reaction of 2,3-O-isopropylidene-D-glyceraldehyde with 2,4,5-trifluorophenylmagnesium bromide gave [(4R)-2,2-dimethyl-1,3-dioxolan-4-yl](2,4,5-trifluorophenyl)methanol in 65% yield as a mixture of diastereoisomers (1-:-1). The Ph3P catalyzed reaction of the latter with C2Cl6 followed by reduction with Pd/C-catalyzed hydrogenation gave (2S)-3-(2,4,5-trifluorophenyl)propane-1,2-diol with >99% ee and 65% yield.
