Glycosylation of a newly functionalized orthoester derivative

Abstract

Tandem glycosylation of the 6-O-Fmoc-substituted benzyl orthoester derivative 2a was carried out in moderate yields by electrogenerated acid (EGA). The Fmoc group was effectively removed under mild basic conditions, and the product was submitted to the subsequent glycosylation. © 2014 by the authors; licensee MDPI, Basel, Switzerland.
