The first DirectedorthoMetalation (DoM) reaction of aryl O-carbamates on polystyrene-divinylbenzene (PS-DVB) resin using a trityl linker is described. Using low temperatures and short metalation times, a range of electrophiles have been introduced to give, after cleavage from support, substituted benzyl alcohols in high purity. [reaction: see text]
