## Abstract As asymmetric route to [^14^C]Ξ²βhydroxycompactin 1 bearing the (__S__)β2βmethylβ[1β^14^C]butanoate side chain has been developed. Methylation of [Nβ[1β^14^C]butyrylβ4β(__S__)βphenylmethylβ2βoxazolidinone 4 afforded a 95:5 mixture of diastereomeric [Nβ(__S,R__)β2βmethylβ[1β^14^C]butyryl]
