The title compound, C~21~H~30~Cl~2~N~4~O, contains a sterically hindered phenol group. The dihedral angle between the two rings is 72.3 (1)°. The propyl chain is disordered over two orientations.
In the title compound, C 27 H 38 O 4 SSi, the furanose ring adopts a nearly perfect E 4 envelope conformation, while the sixmembered ring containing the Si atom exists in an approximate half-chair conformation. The conformation about the glycosidic linkage is that favored by the exo-anomeric effect.
