✦ Synopsis
The new lactosyl donor 8, bearing an Fmoc-protected hydroxy group, has been prepared from lactose for the solidphase synthesis of lactose-containing oligosaccharides. In addition to the preparation of 3b-O-fucosyllactoside 1 (with donor 4), use of this new building block has permitted the syntheses of 3b-O-mannosyllactoside 2 and of human milk [a

Complicated oligosaccharides such as dodecasaccharide 1 can be constructed by a new solid-phase strategy. The attachment to the polymeric support (gray sphere) is through a photolabile linker (structure I), and thioglycosides serve as carbohydrate donors. Bn=benzyl, Bz=benzoyl.
The solid-phase synthesis and characterization of a series of accomplished by means of diisopropylcarbodiimide (DIC)/ hydroxyazabenzotriazole (HOAt). Coupling between amino peptides (4-15) containing reverse-turn mimetic bicyclic lactams is reported. The bicyclic lactams (1a, 1b) possess acids and t
