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].
标题化合物C21H42O5Si2是由(3R,4S,5R)-3,5-双-[(叔丁基二甲基硅基)氧基]-4-羟基环己-1-烯羧酸甲酯通过酯化反应合成的。环己烯环呈半椅式构象。在晶体中，分子通过C—H⋯O氢键相连，形成沿[010]方向延伸的螺旋链。
