Directed ortho metalation (DoM) is an adaptation of electrophilic aromatic substitution in which electrophiles attach themselves exclusively to the ortho- position of a direct metalation group or DMG through the intermediary of an aryllithium compound. The DMG interacts with lithium through a … See more DOM has traditionally been applied to tertiary anilines and benzyl amines. The method has also been applied to the synthesis of enantiopure benzyl amines in scheme 3, which involves ortho-lithiation of tert-butyl phenyl … See more Directed metallation is not limited to lithium intermediates or even to an ortho preference.
