Abstract
Sequential reactions of aminoalkynes represent a powerful tool to easily assembly biologically important polyfunctionalized nitrogen heterocyclic scaffolds. Metal catalysis often plays a key role in terms of selectivity, efficiency, atom economy, and green chemistry of these sequential approaches. This review examines the existing literature on the applications of reactions of aminoalkynes with carbonyls, which are emerging for their synthetic potential. Aspects concerning the features of the starting reagents, the catalytic systems, alternative reaction conditions, pathways and possible intermediates are provided.

Heteroployacid on the composite of boehmite and polyionic liquid as a catalyst for alcohol oxidation and tandem alcohol oxidation Knoevenagel condensation reactions. Sci Rep 2022; 12:16395. [PMID: 36180555 PMCID: PMC9525677 DOI: 10.1038/s41598-022-20699-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 09/16/2022] [Indexed: 11/18/2022] Open
Abstract
Using boehmite as an available and low-cost natural compound, a bi-functional catalytic composite is prepared through vinyl-functionalization of boehmite, followed by polymerization with the as-prepared bis-vinylimidazolium bromide ionic liquid and supporting of phosphotungstic acid. The catalyst was characterized via ICP, XRD, TGA, FTIR, SEM/EDS and elemental mapping analysis and applied for promoting alcohol oxidation reaction and one-pot tandem alcohol oxidation/Knoevenagel condensation reaction in aqueous media under mild reaction condition. The results indicated high catalytic activity of the catalyst for both reactions. This protocol showed high generality and aliphatic, aromatic and heterocyclic alcohols could be applied as substrates to furnish the corresponding products in high to excellent yields. Furthermore, hot filtration test confirmed true heterogeneous nature of the catalysis. The catalyst could also be recovered readily and reused for at least five runs of the reaction with low loss of the activity and phosphotungstic acid leaching upon each run.

Abstract
Quinoline derivatives are frequently found in natural products and biologically active compounds, however, construction of quinoline fused polyheterocycles is the challenging goal in synthetic organic chemistry. In this regard, quinolinium salts meet the demand to a great level, as they can be synthesized readily and employed effectively for the rapid construction of condensed heterocyclic core. The present review focuses on recent (2015-2021) applications of different quinolinium salts that react with suitable partners to access diverse annulated products. Most of the reactions discussed here involve easily available starting materials, operationally simple, high atom efficiency and environmentally benign. Mechanistic aspects of representative transformations have also been highlighted for better understanding of reaction pathway.

Abstract
Numerous metal-catalyzed reactions involving internal alkynes and aimed towards synthetically and pharmacologically important alkenes and heterocycles have appeared in the literature. Among these, Cu-catalyzed reactions have a special place, which has prompted the investigation and development of carbon-carbon and carbon-heteroatom bond-forming reactions. These reactions possess wide scope, and during the paths of these reactions, either stable or in situ intermediates are formed via the addition of Cu as a core catalyst or synergistic catalyst. In this review, we aim to report different contributions relating to Cu-catalyzed reactions of internal alkynes for the synthesis of different valuable alkenes and heterocycles which have appeared in the literature in the last decade. We anticipate that this appraisal will deliver basic insights for the further advancement of Cu-catalyzed reactions in organic chemistry.

Abstract
Herein, we report a protocol for PtI2-catalyzed formal three-component cascade cycloaddition reactions between γ-aminoalkynes and electron-deficient alkynes to afford highly substituted cyclohexadiene-b-pyrrolidines in good yields. On the basis of the results of the control experiments and density functional theory calculations, we present a plausible mechanism that proceeds via two key intermediates. The overall transformation involves the cleavage and formation of multiple C-C and C-N bonds and a previously unreported reaction mode of a seven-membered nitrogen heterocyclic intermediate.

Discovery of seneciobipyrrolidine derivatives for the amelioration of glucose homeostasis disorders through 4E-BP1/Akt/AMPK signaling activation. Eur J Med Chem 2021; 228:113954.

Abstract
Modulating the glucose transport in skeletal muscle is a promising strategy for ameliorating glucose homeostasis disorders. However, the complicated mechanisms of glucose transport make it difficult to find compounds therapeutically relevant molecular mechanisms of action, while phenotypic screening is thought to be an alternative approach to mimic the cell state of interest. Here, we report (±)-seneciobipyrrolidine (1a) is first found to enhance glucose uptake in L6 myotubes through phenotype-based screening. Further SAR investigation led to the identfication of compound A27 (EC50 = 2.7 μM). Proteomiic analysis discloses the unique function mechanism of A27 through upregulating the level of the eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1), subsequently enhancing the Akt and AMPK phosphorylation, thereby promoting the glucose uptake. Chronic oral administration of A27 significantly lowers blood glucose and improves glucose tolerance in db/db mice. This work is new research on seneciobipyrrolidine derivatives, providing a promising avenue for ameliorating glucose homeostasis.

Abstract
Gold-catalyzed bicyclic annulations of 4-methoxy-1,2-dienyl-5-ynes with isoxazoles afford indolizine derivatives; the reaction mechanism involves alkyne attack on a gold π-allene to yield a vinyl gold carbene.
Gold-catalyzed bicyclic annulations of 4-methoxy-1,2-dienyl-5-ynes with isoxazoles afford indolizine derivatives with a structural rearrangement. The mechanism of these new annulations does not involve α-imino gold carbenes generated from gold π-alkyne intermediates. We postulate alkyne attack on gold π-allenes, yielding vinyl gold carbenes. These newly generated carbenes react with isoxazole derivatives to yield Z-3-imino-2-en-1-als, further enabling sequential cyclizations to deliver indolizine derivatives in two distinct classes.
