Organocatalytic dearomatization of β‐naphthols has been achieved via a 1,6‐conjugated addition of 2‐naphthols to alkynyl 7‐methylene‐7H‐indoles in situ generated from α‐(7‐indolyl)methanols. In the presence of racemic phosphoric acid, a series of tetrasubstituted allenes was obtained in high yields. Particularly, with the aid of chiral phosphoric acid, asymmetric dearomatization of β‐naphthols was investigated, affording axially chiral tetrasubstituted allenes with moderate enantioselectivity.

The iron (ІІІ)‐promoted tandem cyclization of 1‐(2‐(allyloxy)aryl)‐1H‐indoles with diselenides has been developed for the preparation of seleno‐benzo[2,3][1,4]oxazepino[4,5‐a]indole derivatives. The investigation to determine the best reaction conditions indicated the use of 1‐(2‐(allyloxy)aryl)‐1H‐indoles (0.2 mmol) with diselenides (1.5 equiv.) and iron(III) chloride (1.5 equiv.) in acetonitrile at room temperature under air, and more than 48 examples were obtained. The reaction features access to selenized 7‐membered containing nitrogen‐oxygen heterocyclic skeleton, which also represents a 7‐exo‐trig cyclization process of 1‐(2‐((2‐methylallyl)oxy)aryl)‐1H‐indoles and diselenides.

Herein, we report a manganese‐catalyzed three‐component vinylation strategy for the synthesis of vinylphosphines from readily available alcohols, sulfones, and phosphines via acceptorless dehydrogenative strategy. This multi‐component, four‐stage, one‐pot protocol offers a stereoselective approach, overcoming the challenges associated with achieving these products through the hydrophosphination of terminal alkynes. The reaction utilizes sulfones and common alcohols to access both (E)‐β‐substituted vinylphosphines (using methanol) and α‐substituted vinylphosphines (using primary alcohols) in yields ranging from 52% to 99%, with E:Z stereoselectivity of 95:5 to 99:1. Importantly, the synthesized branched‐substituted vinylphosphines exhibited superior ligand performance in the copper‐catalyzed cross‐coupling of aryl bromides with pyrazole compared to the commercially available PPh3 and diphenyl(vinyl)phosphane.

An asymmetric 1,4‐reduction of exocyclic α,β‐unsaturated ketones, yielding diverse optically active α‐substituted tetralones, has been achieved using a chiral SPINOL‐derived borophosphate catalyst. The enantioselectivity‐determining step of the reaction involves the protonation of a highly active boron enolates intermediate. This catalytic reduction system, comprising chiral SPINOL‐derived borophosphate and pinacolborane, has potential for broader application in other asymmetric reduction reactions.

Herein, we describe an approach to the synthesis of 3‐hydroxyisoindolinone derivatives via copper‐catalyzed tandem cyclization of 2‐(alkynylaryl)acetonitriles and amines. This reaction is compatible with 2‐(alkynylaryl)acetonitriles and primary alkyl amines containing various functional groups, providing the corresponding 3‐hydroxyindolinone derivatives with yields ranging from 44%–82%. Preliminary mechanistic studies suggest that the reaction involves oxidation of the benzylic carbon, amide formation, hydration of the alkyne and intramolecular cyclization to produce various 3‐hydroxyisoindolinones. The practicality of the strategy was further demonstrated by gram‐scale synthesis, late‐stage functionalizations, and the post modification of natural products.

The role of ligands in catalytically active metal complexes can be crucial. Herein, we present a study on the synthesis and catalytic behavior of alkaline earth bisguanidinato complexes. The reactivity of trisubstituted guanidines, specifically (iPrHN)2CNR (R=Ph, 2‐Ph2PC6H4, 2‐MeSC6H4), towards magnesium and calcium alkyls or amides was explored. All the compounds were found to be very active in the hydroboration of acetophenone with pinacolborane. Notably, a calcium‐based complex was especially effective in the hydroboration of carbonyl compounds, demonstrating significant chemoselectivity against other reactive functional groups. This complex was also particularly effective in the double hydroboration of nitriles and moderately active in the hydroborative dearomatization of pyridine. Our experimental and DFT studies allow us to propose a mechanism in which the participation of the guanidinato ligands, along with the metal, is key to the activation of both the unsaturated species and borane.

Well‐defined (P,C)‐cyclometalated Au(III) complexes proved to be able to catalyze the synthesis of coumarins by intramolecular hydroarylation of a broad range of aryl propiolates under mild and practical conditions (0.1–2 mol% catalyst, 25–40 °C, 1–24 hours). The use of an ionic liquid as reaction solvent allowed to drastically decrease the amount of Brönsted acid used to unlock the catalyst regeneration step. The effect of the nature of the acid additive and of the ionic liquid anion have been assessed. Preliminary results on the extension of this methodology to the cyclization of aryl propargyl ethers are also presented.

We disclose the intramolecular synthesis of 3‐alkenyl‐2H‐indazoles from 2‐alkynylazobenzenes, promoted by a dual catalysis using AuCl3 and a ruthenium photocatalyst under visible light irradiation. This reaction proceeds through hydroamination of the alkynyl fragment. The yields are influenced by electronic factors. Control experiments suggest that both radical and polar mechanisms operate in parallel. This transformation involves C−N bond formation and a 1,2‐hydride shift. Additionally, derivatization was performed to demonstrate the versatility of this methodology.

The synthesis of indolizine derivatives was achieved through the reaction of pyridinium 1,4‐zwitterionic thiolates with a diverse array of 2‐methyl‐2‐nitro‐3‐aryloxiranes. Subsequent investigations unveiled a synthetic route to indolizines via a stepwise [(5+1)−1] pathway, with unstable pyridothiazines serving as transient intermediates. DFT calculations elucidated that this transformation entails sequential annulation, deacylation, desulfurization, and oxidation steps.
