Transition Metal Catalysed Functionalisation at the Anomeric Center of Carbohydrates

Abstract
There has been an increasing interest during the last thirty years in the development of homogeneous organometallic catalysis in organic chemistry.1 This is probably due to the high observed stereo- and regioselectivities of these methods and the mildness of the reaction conditions. Even reactions that otherwise would not occur have been reported possible in the presence of a metal catalyst. So the use of organometallic catalysis, and particularly that involving transition metals, has produced a number of new and powerful synthetic methods for important classes of compounds, some in optically active form.
