Summary: The reaction of phosphorus(III) esters with pinacolborane using an NHC-copper(I) catalyst allows for the quick generation of various phosphines, which can be further used in the synthesis of different phosphorus-containing compounds. This telescoped approach provides access to a range of P-H bonded species with high conversions, enabling the synthesis of diverse phosphorus-based molecules without the need to handle toxic compounds.

Summary: Substituted oxazoles and imidazoles can be synthesized in one pot using the isocyanide building block Asmic, an alkyl halide, and an acid chloride or nitrile. The modular assembly involves sequential deprotonation-alkylation and deprotonation-acylation or imination of Asmic, followed by a unique carbon-sulfur bond cleavage to construct the azole. This strategy is robust, highly efficient, and allows for the formation of C4-C5 disubstituted oxazoles or imidazoles in a single operation.

Summary: This article describes a one-pot approach for the synthesis of tricyclic indolizines using a bicyclic imidazole-alcohol catalyst. The method is based on an aqueous Morita-Baylis-Hillman reaction, followed by intramolecular cyclization and dehydration, resulting in the formation of two new bonds (C-C and C-N) in simple conditions. The cyclization efficiency depends on the size of the cycloalkenone ring.

Summary: Quinoxalines are nitrogen-containing bicyclic heterocycles with diverse biological activities and luminescence properties. Their syntheses involve a range of multicomponent methods, such as Ugi-reactions, leading to the development of novel reactions and sequences. Diversity-oriented synthesis and transition metal catalyzed multicomponent reactions offer efficient pathways to quinoxalines and quinoxaline-containing moieties.

Summary: Chiral 3,4-dihydrocoumarin derivatives were synthesized in moderate to high yields with excellent enantioselectivity (up to 96% ee) via a one-pot cascade reaction using a binaphthyl-modified squaramide bifunctional organocatalyst. The reaction involved C-H oxidation and cyclization of 2-benzyl phenols and oxazolones under mild conditions.

Summary: A new method for the annulation of a thiopyrane ring to an indole core under mild conditions has been developed. The reaction mechanism involves a stepwise addition through ion-pair formation, with the essential role of the Li atom at all stages of the process being revealed by AIM calculations.

Summary: A one-pot reaction has been successfully used to synthesize a five-membered ring with a metal vinylidene structure. The strain and stability of the cyclic metal vinylidene complexes have been analyzed experimentally and computationally. The metal vinylidene unit is unreactive to nucleophiles and electrophiles but reacts at the nearby carbonyl group.

Summary: The one-pot combination of halogenation biocatalysis and Suzuki-type cross coupling enables the direct arylative cyclization of allenic alcohols with boronic acids. A novel heterogeneous nanobiohybrid was developed, consisting of an oxidase matrix hosting small spherical palladium nanoparticles, exhibiting catalytic competence for both the biocyclization as well as the C-C bond-forming cross coupling, underlining the potential of this new techniques for streamlining chemoenzymatic approaches.

Summary: An efficient method for the synthesis of 1,4-benzothiazinone-3-one derivatives via a potassium carbonate and copper-mediated C-S and C-N Ullmann coupling reaction between 2-bromothiophenol and 2-haloacetanilide is reported. This approach eliminates the need for noble metals and expensive ligands, making it a simple and cost-effective strategy.

Summary: A new one-pot synthesis of polysubstituted carbazoles starting from beta-nitro-beta,gamma-unsaturated-ketones and indoles was reported. The process involved a Friedel-Crafts reaction of indoles to nitroolefins supported by 2,2,2-trifluoroethanol (TFE) followed by an acidic-promoted and microwave-assisted intramolecular cyclization, resulting in products with satisfactory to good overall yields (55-78%).

Summary: This study achieves enantioselective and diastereoselective synthesis of densely substituted chiral pyran derivatives by using amino-thiourea or quinine organocatalyst under ball-milling conditions. Liquid-assisted grinding proves to be a highly efficient means of obtaining pyrans in high yield, with high enantiomeric purities and short reaction times.
