Boron trifluoride, debenzylation with

Dealkylation of Ethers. The combination of an aliphatic thiol such as ethanethiol and boron trifluoride etherate has been used to remove benzyl groups. However, although that method works well it does suffer from an incompatibility with certain functional groups. The presence of an a,/3-unsaturated ester in the same molecule can result in Michael addition as well as debenzylation (eq 1). Boron trifluoride in the presence of dimethyl sulfide, being a milder reagent, does not cause this type of complication, as shown in eq 2. ... [Pg.87]
