TL;DR: This paper treated 4-aryl-2,4-dioxobutanoic acids with aromatic amines, 4-aminoantipyrine, and benzophenone hydrazone furnished N-substituted 2amino-4-aryl -4-oxo-2-butenoic acids.
Abstract: Treating 4-aryl-2,4-dioxobutanoic acids with aromatic amines, 4-aminoantipyrine, and benzophenone hydrazone furnished N-substituted 2-amino-4-aryl-4-oxo-2-butenoic acids that existed in solutions in enaminoketone and iminoketone forms. The acids obtained underwent in the presence of acetic anhydride cyclization into N-substituted 5-aryl-3-imino-3H-furan-2-ones.

TL;DR: A new approach for the solid-phase synthesis of indoles 1 is described that involves a one-pot release and cyclization reaction of a solid-supported hydrazone through a Wang-type linker and accomplished the synthesis of 40 naltrindole derivatives.
