One-pot mechanosynthesis of aromatic amides and dipeptides from carboxylic acids and amines

Environmentally friendly one-pot synthesis of amides, bis-amides and dipeptides by mechanochemical carbodiimide-mediated coupling of carboxylic acids and amines is described; high reaction yields and simple aqueous work-up allow for the clean, practical and fast preparation of a variety of compounds containing the amide bond from readily accessible reagents.
