A new efficient method for the cleavage of benzyl carbamates (CBZ protective groups) is described that involves a hard acid (BFs.OE&) -soft nucleophile (EtSH) system. Unlike other available methods, this combination avoids the reduction of olefias, acetylenes, imines, halides and nitro groups, or th
