In the presence of nonracemic bis(triisopropylphenyl) binaphthylphosphoric or octahydrobinaphthylphosphoric acids, racemic (phenoxycarbonyl)amino alcs. such as RCH(OH)CH2NHCO2Ph [R = Ph, 2-naphthyl, 1,3-benzodioxol-5-yl, 2-thienyl, (E)-PhCH:CMe, i-Pr, cyclohexyl, t-Bu, TBSOCMe2, 2-hexyl-1,3-dithiane-2-yl] underwent enantioselective acetalization and kinetic resolution with 2,3-dihydrofuran to yield nonracemic amino alcs. (R)-RCH(OH)CH2NHCO2Ph [R = Ph, 2-naphthyl, 1,3-benzodioxol-5-yl, 2-thienyl, (E)-PhCH:CMe, i-Pr, cyclohexyl, t-Bu, TBSOCMe2, 2-hexyl-1,3-dithiane-2-yl; TBS = tert-butyldimethylsilyl] and (S)-O-2-tetrahydrofuranylated amino alcs.; the alcs. were isolated in 32-50% recoveries and in 94-99% ee.
