The enantioselective reduction of the oxazolidinone (I) with BH3/SMe2 and a chiral borinated catalyst gives the (S)-alcohol (II), which is condensed with the labeled imine (III) (prepared by reaction of 4-fluoroaniline (IV) and 14C-labeled 4-hydroxybenzaldehyde (V)) by means of TiCl4 in dichloromethane to yield the silylated adduct (VI) (previously the reactants are silylated with Tms-Cl and DIEA). Finally, adduct (VI) is resilylated with bis(trimethylsilyl)acetamide and cyclized and desilylated by treatment with TBAF in dichloromethane to afford the target 14C-labeled SCH-58235.
