A series of hindered and/or labile alcohols has been derivatized with a variety of acylating and silylating agents using pyridine in methylene chloride at 15 kbar (1.5 GPa) pressure to afford excellent yields of protected alcohols at 20 "C, largely without the need for added DMAP. Methoxyethoxymeth
