metalation-electrophile quench of 1,2- and 1,4-O-carbamates (Scheme 2) and iterative metalation procedures (Scheme 3) is presented. The results provide new methodology for the synthesis of functionalized contiguously 1,2,3- and 1,2,3,4-substituted aromatic derivatives of difficult accessibility and potential broad utility. A comparison of the present methodology with previously developed routes is given in selected
