✦ Synopsis

Two new C9 protecting groups for the anomeric position of carbohydrates are reported. Methods both for their introduction and removal are described. The C9-protected compounds are much less polar than the corresponding allyl protected analogues. The new protecting group chemistry has been used to prepare compound 17 en route to a disacchande analogue of the antibiotic moenomycin A.
