Journal of the American Chemical Society(20),   Traditionally, access to structurally defined complex carbohydrates has been very laborious.

Although recent advancements in solid-phase synthesis have made the construction of complex oligosaccharides less tedious, a high level of technical expertise is still necessary to obtain the desired structures. We describe the automated chemical synthesis of several oligosaccharides on a solid.

Glycosylations: a) 2 × 5 equiv TMSOTf, ACN/DCM (), −50 °C (5 min), −30 °C (10 min), −20 °C (80 min), −10 °C (10 min), 0 °C (10 min) for 4 and 5.b) 2 × 5 equiv TfOH, NIS, DCM, −40 °C (5 min), −20 °C (30 min) for 6 and 7.c) 2 × 5 equiv TMSOTf, DCM/dioxane (), 20 °C (90 min.

In some cases, synthesis of oligosaccharides on supports is more efficient than the corresponding synthesis in solution, although this cannot still compare favourably with the latter. Examples of successful solid-phase syntheses of complex oligosaccharides and glycoconjugates are given.
