Carbohydrates have been shown to play important roles in biological processes. The pace of development in carbohydrate research is, however, relatively slow due to the problems associated with the complexity of carbohydrate structures and the lack of general synthetic methods and tools available for the study of this class of biomolecules. Recent advances in synthesis have demonstrated that many of these problems can be circumvented. In this Review, we describe the methods developed to tackle the problems of carbohydrate‐mediated biological processes, with particular focus on the issue related to the development of the automated synthesis of oligosaccharides. Further applications of carbohydrate microarrays and vaccines to human diseases are also highlighted.

Sweet dreams: Carbohydrates play important roles in biological processes. The pace of carbohydrate research is, however, relatively slow due, amongst other things, to the lack of general synthetic methods. Current developments in the automated synthesis of oligosaccharides can help overcome many of these problems and to pave the way for biomedical applications.
