C(1→4)-Linked Disaccharides Through Carbonylative Stille Cross-Coupling. —
synthesis of C(1→4)-linked diglycosides containing a central dienone moiety like
25- 192 The
(IV) is achieved by carbonylative Stille cross coupling of a tinglucal (I) with a glycosyl
triflate (II) under carbon monoxide atmosphere. In a similar manner, the synthesis of a
C(1→1)-linked diglycoside (IX) is successfully achieved. The regio- and stereoselective hydrogenation of the central dienone unit of compound (IV) is presented in three
consecutive steps. — (STEUNENBERG, P.; JEANNERET, V.; ZHU, Y.-H.; VOGEL*,
