Published: May 2013

The title compound, C21H42O5Si2, was synthesized from (3R,4S,5R)-methyl 3,5-bis-[(tert-butyl-dimethyl-sil-yl)-oxy]-4-hy-droxy-cyclo-hex-1-ene-carboxyl-ate by an esterification reaction. The cyclo-hexene ring adopts a half-chair conformation. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming helical chains propagating along [010].
