Is acyl migration to the aglycon avoidable in 2-acyl assisted glycosylation reactions?

This report unequivocally separates orthoester formation from acyl transfer for the first time and indicates possible routes to eliminate 2-O-acyl transfer during glycosylation reactions. Experimental evidence is shown that acyl transfer from 2-O-acyl-3,4
