Thiamphenicol is a widely used antibiotic that exhibits activity against numerous Gram-positive and Gram-negative pathogens. Here, we describe the expedient synthesis of its four stereoisomers through a dynamic kinetic resolution that follows a ruthenium-catalyzed asymmetric hydrogenation or a hydrogen transfer reaction as the key step.

N-Benzoylcarbamates formed in situ from 2,3-epoxyalcohols and PhCONCO undergo clean to C-2 cyclisation followed by N to O acyl migration on treatment with catalytic sodium imidazolide or other bases.Subsequent benzoate cleavage (NaOMe) is accompanied by equilibration of the N-unsubstituted oxazolidinones; cleavage without significant isomerisation is achieved with MeLi or Zn(BH4)2.This methodology is applied in a diastereospecific, 6-step conversion of methyl 4-bromophenyl sulfonate to racemic Thiamphenicol.
