Optional Site Selectivity in the Metalation of o- and p-Anisidine through Matching of Reagents with Neighboring Groups
N-Protected o- and p-anisidines (2- and 4-methoxyanilines) undergo a hydrogen/metal exchange at the position adjacent to either the oxygen or nitrogen atom depending on what organometallic base is employed. These synthetically useful findings support previous views about neighboring group/reagent interactions. [on SciFinder (R)]
