A radical-mediated three-component 1,4-sulfonylarylation of 1,3-enynes with aryl iodides and sulfinate salts using cooperative photoredox/nickel catalysis is described. This protocol enables the synthesis of tetrasubstituted sulfonyl-containing allenes under redox-neutral conditions and provides a versatile 1,3-enyne 1,4-difunctionalization platform for the synthesis of a diverse range of tetrasubstituted allenes with high chemo- and regioselectivities, excellent functional group tolerance, and a broad substrate scope.

Abstract
A straightforward, user-friendly, efficient protocol for the one pot, ZnI2-catalyzed allenylation of terminal alkynes with pyrrolidine and ketones, toward trisubstituted allenes, is described. Trisubstituted allenes can be obtained under either conventional heating or microwave irradiation conditions, which significantly reduces the reaction time. A sustainable, widely available, and low-cost metal salt catalyst is employed, and the reactions are carried out under solvent-free conditions. Among others, synthetically valuable allenes bearing functionalities such as amide, hydroxyl, or phthalimide can be efficiently prepared. Mechanistic experiments, including kinetic isotope effect measurements and density functional theory (DFT) calculations, suggest a rate-determining [1,5]-hydride transfer during the transformation of the intermediate propargylamine to the final allene.

Abstract
The unexpected gold-catalyzed formal [3+2]-cycloaddition of N-2,2,2-trifluoroethylisatin ketimines with 2-(1-Alkynyl)-2-alken-1-ones is reported. Both diastereomers of the corresponding cycloadducts were formed in moderate to excellent yields with excellent diastereoselectivities by switching the catalytic system from mono-gold to gold/silver bimetallic catalytic system. The practicality of this protocol is demonstrated by scale-up reaction and the transformations of the cycloadduct.

Abstract
For the first time, the literature data on the methods of synthesis and reactivity of 3-(1-alkynyl)chromones are summarized and systematized. The main method for obtaining these compounds is the Sonogashira cross-coupling reaction of 3-halochromones with terminal acetylenes, and their most important chemical properties include the transformation into furans, reactions with dinucleophiles, ambiphilic [4+2]- and [4+3]-cyclizations, and also dimerization and mixed condensation of 2-methyl-3-(1-alkynyl)chromones due to the vinylogous methyl group. Except for the oxacyclization to furans, chemical transformations of 3-(1-alkynyl)chromones are accompanied by pyrone ring transformation, in which not only the carbonyl group but also the triple bond can participate. This significantly increases the synthetic value of these compounds and ensures the production of more complex heterocyclic systems based on them. The mechanisms of the reactions are discussed, the conditions for their implementation and the yields of the resulting products are indicated.
The bibliography includes 80 references.

Abstract
A small-molecule collection with structural diversity and complexity is a prerequisite to using either drug candidates or chemical probes for drug discovery and chemical-biology investigations, respectively. Over the past 12 years, we have engaged in developing efficient diversity-oriented cascade strategies for the synthesis of topologically diverse skeletons incorporating biologically relevant structural motifs such as O- and N-heterocycles, fused polycycles, and multifunctionalized allenes. In particular, we have highlighted the use of simple, linear, and densely functionalized molecular platforms in these reactions.This account details our efforts in the design of novel molecular platforms for use in metal- and organo-catalyzed cascade reactions, which include 2-(1-alknyl)-2-alken-1-ones (yne-enones) for heterocyclization/cross-coupling cascades, heterocyclization/cycloaddition cascades, nucleophilic addition/cross-coupling cascades, nucleophilic addition/heterocyclization cascades, and so on. Moreover, this Account outlines corresponding mechanistic insights, computational information, and applications of these cascades in the construction of various highly substituted carbo- and heterocycles as well as highly functionalized acyclic compounds, e.g., allenes and dienes. In addition to yne-enones, we evolved the functional groups of our original yne-enones to provide a series of yne-enone variants, which resulted in products with complementary reactivities.The reactivity profile of the yne-enones is defined by the presence of an alkyne moiety and a conjugated enone unit and their mutual through-bond connectivity. Owing to the conceptually rapid development of carbophilic activation, we have identified a series of efficient catalytic systems consisting of metal catalysts, including Pd, Au, and Rh complexes, for diversity-oriented cascade catalysis, allowing various unprecedented reactions to be achieved through different-types of reaction intermediates, including all-carbon metal 1,n-dipoles, furan-based o-quinodimethanes (oQDMs), and allenyl-metal species. In addition to commonly known transition-metal catalytic activity, the Lewis acidity of these complexes is crucial to accomplish the corresponding transformation. In addition, highly enantioselective gold(I)-catalyzed heterocyclization/cycloaddition cascades of yne-enones and their variants were achieved by the application of bisphosphines (e.g., Cn-TunePhos), monophosphines, and our developed "Ming-Phos" as chiral ligands. Importantly, Ming-Phos ligands exhibited excellent performance in gold-catalyzed mechanistically distinct [3 + n]-cycloaddition reactions, in which the chiral sulfinamide moiety is possibly responsible for the interaction with the substrate to control enantioselectivity. Subsequently, we demonstrated that the easily prepared polymer-supported Ming-Phos ligand could be applied for heterogeneously gold(I)-catalyzed asymmetric cycloaddition with good stereocontrol. With metal-free catalysis, the divergent functionalization of yne-enones provides numerous synthetic outlets for structure diversification. For example, yne-enones are particularly attractive for use as precursors of various chiral and achiral heterocycles, such as pyrazoles, isoxazoles, pyrroles, and pyrans, etc.

Abstract
Various new transformations of gem-difluoroalkenes leading to trifluoromethyl substituted compounds have been well established in the past years. However, the development of new transformations of gem-difluoroenynes lags much behind. Herein is reported the fluoroarylation of 1,1-difluoro-1,3-enynes with aryl halides in the presence of silver fluoride affording trisubstituted trifluoromethyl allenes under the catalysis of palladium. The reaction features mild conditions, high functional-group tolerance, and high regioselectivity.

Abstract
The rapid enantioselective synthesis of valuable building blocks and pharmaceutically important compounds from easily accessible precursors is one of the major areas of focus in organic chemistry. In this context, 2-activated 1,3-enyne has emerged as a powerful synthon in recent years for the efficient synthesis of enantioenriched furans, allenes, 4-H-pyrans, and 4-isoxazolines, which are privileged scaffolds in bioactive compounds and natural products. This review will cover the history of the development of 2-activated 1,3-enyne in enantioselective synthesis along with the corresponding mechanisms, which may motivate further development in this area to forge more complex and valuable molecules.

Abstract
Classical 1,4-dicarbofunctionalization of 1,3-enynes employs organometallic reagents as nucleophiles to initiate the reaction. We report a copper-catalyzed 1,4-alkylarylation of 1,3-enynes with alkyl diacyl peroxides as masked alkyl electrophiles and aryl boronic acids as nucleophiles, selectively affording structurally diversified tetrasubstituted allenes under mild conditions. Mechanistic studies suggest that an allenyl radical might be involved.

Abstract
An Et(3)N-catalyzed tandem reaction of electron-deficient 1,3-conjugated enynes with hydroxylamines was developed which provided rapid, metal-free, and regioselective access to highly substituted multifunctionalized 2,3-dihydroisoxazoles under mild conditions. The reactions of 3-(2-arylethynyl)-4H-chromen-4-ones with hydroxylamines afford beta-amino enones under the same reaction conditions.
