achieved with high chemoselectivity. In addition, several control experiments revealed that a phenolic hydroxygroup was silylated much faster than a primary alcohol in both an inter- and intramolecular manner. The reactivity toward silylation under these systems might stem from the pKa of the hydroxygroup.
