A practical large-scale access to 1,6-anhydro-β-D-hexopyranoses by a solid-supported solvent-free microwave-assisted procedure

Microwave irradiation of 6-O-tosyl or 2,6-di-O-tosyl peracetylated hexopyranoses absorbed on basic alumina in a dry medium afforded the corresponding 1,6-anhydro-β-D-hexopyranoses. A direct access to 1,6:3,4-dianhydro-β-D-altropyranose (16) from D-glucose is also described.
