A highly stereoselective synthesis of β-olivosides by glycosidations of 2-iodo-olivosyl fluoride using montmorillonite K-10 as an environmentally benign solid acid

The novel and highly beta-stereoselective glycosidations of a 2-iodo-olivosyl fluoride and alcohols using a heterogeneous and environmentally benign solid acid, montmorillonite K-10, have been developed to afford the corresponding 2-iodo-beta-olivosides in high yields with high stereoselectivities.
