(Tetrahydrofuran-3-yl) methanol enantiomers were converted to two (tetrahydrofuran-3-yl) methyl-camphor sulfonate diastereomers with (D)-(+)-10-camphorsulfonic chloride, the diastereomers were then separated by kinetic resolution to get (+)-(tetrahydrofuran-3-yl) methyl-camphor sulfonate. The separated (+)-(tetrahydrofuran-3-yl) methyl-camphor sulfonate was dissociationed with sodium hydride/benzyl alcohol to give (S)-(+)-(tetrahydrofuran-3-yl) methanol, The ee value >99, the yield is 85%, Further reaction with (1,5-Dimethyl-[1,3,5]triazinan-2-nitro imino)-hydrazine to prepare (S)-(+)-dinotefuran.
