✦ Synopsis


The title compound, C 28 H 41 NO 6 , was obtained by reduction of benzyl 2-deoxy-2-(3,5-di-tert-butylsalicylideneamino)--dglucopyranoside. The benzyl substituent is in an axial position, whereas the 3,5-di-tert-butylsalicylamino substituent and the hydroxyl groups are in equatorial positions. The enantiomerically pure title compound is a potential O,N,O-chelate ligand suitable as a precursor for chiral transition metal complexes. The absolute configuration was determined by NMR experiments.

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.
