Construction of Multifunctional 3-Amino-2-carbamimidoylacrylamides and Their Crystalline Channel-Type Inclusion Complexes.

3-Amino-2-carbamimidoylacrylamides were efficiently prepared via a copper(I)-catalyzed three-component reaction of sulfonylazides, propriolamides, and amidines. The synthesized compounds provided three kinds of crystalline structures based on the position of halogen. Two of them presented channel-type inclusion complexes with ethyl acetate through intermolecular hydrogen bonding, intermolecular C-H···π and π-π interactions, and van der Waals forces.
