The nitrogenmustard gas moiety is present as a basic, amine-containing side chain in numerous pharmacophore scaffolds engaging in crucial interactions with targeted biological macromolecules. Herein, a one-pot synthetic approach for the easy introduction of nitrogen mustard-like moieties through dialkyl carbonate chemistry into different phenolic substrates is reported. The scope and limitations of
