(3R,4S,5R)-Methyl 3,5-bis­[(tert-butyl­dimethyl­sil­yl)­oxy]-4-meth­oxy­cyclo­hex-1-ene­carboxyl­ate

R. Liu, Y. Shi, C.-X. Xu and Y.-L. Li

Abstract: The title compound, C21H42O5Si2, was synthesized from (3R,4S,5R)-methyl 3,5-bis­[(tert-butyl­dimethyl­sil­yl)­oxy]-4-hy­droxy­cyclo­hex-1-ene­carboxyl­ate by an esterification reaction. The cyclo­hexene ring adopts a half-chair conformation. In the crystal, mol­ecules are linked via C-H...O hydrogen bonds, forming helical chains propagating along [010].
