Vilsmeier Several diamide derivatives containing 2-chloroquinoline scaffolds were synthesized via Ugi reaction of 2-chloroquinoline-3-carboxaldehydes, amines, carboxylic acids and isocyanides. The diversity of these quinolinyl Ugi-adducts was increased by using 2-chloroquinoline-3-carboxylic acids as a source of acid. Among them, compounds 2d, 2n, 2p, 4a, 4c and<strong...
