New three-component domino reaction providing divergent approaches to multifunctionalized fusedpyrroles with differentsubstitutedpatterns have been established (40 examples). The direct C(sp3)–N bond formation was achieved through intermolecular allylic amination in a one-pot operation, and N-arylation of amines was realized by varying N-amino acidenaminones. The reaction is easy to perform simply

pairs were synthesized via Brønsted acid-promoted domino reactions between indoline-2,3-dione and C2-tethered indol-3-yl enaminones. The reactions were further expanded to prepare C-tethered fused acridine/pyridine pairs, N-substituted amino acids, N-cyclopropyl and N-aryl substituted fused acridine derivatives, as well as bis-furan-3-yl-substituted indoles. During these reaction processes, the domino

A series of novel fused pyrrole derivatives was synthesized by one-pot three-component reaction of β-enaminoketones, derived from cyclohexane-1,3-dione or dimedone, arylglyoxal hydrates, and 1,3-dimethylbarbituric acid in EtOH.

A series of functionalized 4,5,6,7-tetrahydroindol-4-one derivatives containing a residue derived from β-dicarbonyl compound at position 3 were prepared by a reaction of cyclic enaminones, arylglyoxal hydrates, and β-dicarbonyl compounds. Modification of acetylacetone residue at position 3 of tetrahydroindoles was accomplished by condensation with 1,2- and 1,4-bisnucleophiles.
A series of new, N-substituted azapodophyllotoxin derivatives were synthesized via a three-component reaction of an aldehyde, an enaminone and tetronic acid in glacial acetic acid, undermicrowaveirradiation, without a catalyst. This new protocol has the advantages of shorter time, higher yields, lower cost and broader substrate scope, as well as easier operation.
