Abstract
Enols are used for the first time in a condensation with aldehydes and isocyanides to selectively give three- or pseudo-four-component adducts, depending on the reaction conditions. These new transformations have proven to be a convenient alternative for the synthesis of biologically relevant pyrrolidinones containing peptidic or pseudo-peptidic groups on carbon 3. More importantly, this work attests to the utility of heterocyclic enols containing conjugated electron-withdrawing groups as useful reagents in isocyanide-based multicomponent reactions.

Abstract
A catalytic enantioselective entry to β2, 2 -amino acids enabling their direct coupling with nucleophiles is described. The approach is based upon an effective bifunctional Brønsted base catalyzed construction of a quaternary carbon stereocenter at C4 position of pyrrolidin-2,3-diones. Subsequent regioselective Baeyer-Villiger oxidation of the resultant adducts gives β2, 2 -amino acid N-carboxyanhydrides as the reactive species, which can further react with nucleophiles. Following this strategy both, β2, 2 -amino acid derivatives with different functionalities at the newly created stereocenter, and spirocyclic structures can be efficiently prepared.

Abstract
We previously reported the novel efficient proton/heat-promoted four-component reactions (4CRs) of but-2-ynedioates, two same/different primary amines, and aldehydes for the synthesis of tetra- and pentasubstituted polyfunctional dihydropyrroles. If aromatic and aliphatic amines were used as reagents, four different series of products should be obtained via the permutation and combination of aromatic and aliphatic primary amines. However, only three/two rather four different series of tetra-/pentasubstisuted dihydropyrroles could be prepared via the proton/heat-promoted 4CRs. Herein, Cu(OAc)2·H2O, a Lewis acid being stable in air and water, was found to be an efficient catalyst for the 4CR synthesis of all the four different series of tetra-/pentasubstisuted dihydropyrroles. The copper-catalyzed 4CR could produce target products at room temperature in good to excellent yields. Interestingly, benzaldehyde, in addition to being used as a useful reactant for the synthesis of pentasubstituted dihydropyrroles, was found to be an excellent additive for preventing the oxidation of aromatic amines with copper(II) and ensuring the sooth conduct of the 4CRs for the synthesis of tetrasubstituted dihydropyrroles with aryl R(3). In addition, salicylic acid was found to be needed to increase the activities and yields of the copper-catalyzed 4CRs for the synthesis of petasubstituted diyhydropyrroles. On the basis of experimental results, the enamination/amidation/intramolecular cyclization mechanism was proposed and amidation is expected to be the rate-limited step in the copper-catalyzed 4CRs.

Abstract
Heterocyclic enols are used for the first time as acid components in an Ugi-type multicomponent condensation. For that purpose, we have chosen enols containing a Michael acceptor, in order to facilitate an irreversible rearrangement of the primary Ugi adduct. The new four-component process leads readily and efficiently to heterocyclic enamines containing at least six elements of diversity.

Abstract
Tetra- and pentasubstituted polyfunctional dihydropyrroles have been concisely synthesized in high yields by two different processes of the one-pot multicomponent reactions (MCRs) of but-2-ynedioates 1, amines 2, and aldehydes 3 at room temperature or at 70 degrees C. The first one involves a domino hydroamination/nucleophilic addition/amidation-cyclization process and leads to the formation of tetrasubstituted polyfunctional dihydropyrroles 4. The second undergoes hydroamination/amidation/intramolecular cyclization/imine-enamine tautomerization sequence and results in pentasubstituted products 5. The structures of 4 and 5 were confirmed by single-crystal X-ray diffraction. These novel methodologies provide easy access to diversely multisubstituted polyfunctional dihydropyrrole libraries. The primary biological screening in vitro against HIV-1 has shown that 22 tested compounds have exhibited significant activity with IC(50) in micromolar range (38-58 microM).
