with ammonia in benzene or xylene with simultaneous distillation of the water formed in the form of an azeotrope. The enamines obtained enter smoothly into reaction with diethyl acetals of dimethylformamide (III) and dimethylacetamide (IV) with the formation of the corresponding enamidino ketones (Va-c, Via-c). Thus, cyclohexene derivatives unsubstituted at the 5-position (Va, Via) were obtained in the

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.

Efficient domino approaches for the synthesis of multifunctionalized tricyclic fused pyrroles and dibenzo[b,e][1,4]diazepin-1-ones have been established. The reaction pathways were controlled by varying enaminones with different substituted patterns to give a series of new fused pyrroles and dibenzo[b,e][1,4]diazepin-1-ones selectively. The complete anti diastereoselectivity was achieved for the first
