the highly chemoselective benzylation of propargylichydroxygroups in the presence of other hydroxygroups under very usual conditions involving benzyl bromide and sodium hydroxide in DMF at room temperature. This methodology has a high synthetic utility for the selective protection of hydroxygroups at the propargylic position among various other hydroxygroups in complex molecules.
