Abstract
An efficient B(C6F5)3-catalyzed multicomponent reaction of 2,3-diketoesters, amines, allenes, and nucleophiles was reported, which afforded 2α-functionalized pyrroles in moderate to good yields. The reaction features low catalyst loading, usage of a small amount of solvent, high atom economy, tunable installation of diverse functional groups at 2α-position, and water being formed as the byproduct. This is the first multicomponent reaction that combines vicinal tricarbonyl compounds with allenes.

Abstract
Multi-component synthesis of functionalized pyrrole derivatives was achieved via a fourcomponent
condensation reaction of ethyl acetoacetate/ methyl acetoacetate, aromatic amines, nitromethane,
and aromatic aldehydes using triethanolammonium acetate ([TEAH][OAc]) ionic liquid as a
green solvent and catalyst. Easy access to highly substituted pyrroles, reusability of the catalyst, broad
substrate scopes, no column chromatography, short reaction time, good yields of products and solventfree
conditions make this protocol environmentally friendly and practically attractive.

Abstract
Pyrroles and quinolones represent core structures, which are routinely found in both natural and synthetic bioactive substances. Consequently, the development of efficient and regiospecific methods for the preparation of such heterocycles with unique functionality is of some importance. We describe herein the regiospecific synthesis of 1,2,3,4-tetrasubstituted pyrroles containing polar substituents and such products are prepared from vinylogous carbamates and vinylogous aminonitriles. We also describe the regiospecific synthesis of 3-aryl containing 1,3,6trisubstituted quinolones from vinylogous carbamates. The use of an amine exchange reaction to prepare precursors for the pyrrole and quinolone forming cyclizations represents a key factor in the strategy.
