(3R*,4S*)-4-[(S*)-2-Cyclohexyl-2-(tert-butyldimethylsiloxy)ethyl]-3-hexyl-3-(trimethylsilyl)oxetan-2-one

The relative stereochemistry of the substituents of the oxetanone ring in the title compound, C₂₆H₅₂O₃Si₂, prepared by the highly diastereoselective [2 + 2] cycloaddition of a silylketene and a 3-alkoxy-substituted aldehyde, has been established.
