Electrocatalytic Synthesis of gem -Bisarylthio Enamines and α-Phenylthio Ketones via a Radical Process under Mild Conditions

The novel method for the synthesis of gem -bisarylthio enamines and α-phenylthio ketones was developed via the coupling of α-substituted vinyl azides with thiols in the presence of tetrabutylammonium iodide (TBAI) as a redox catalyst and electrolyte at ro

Zn-ProPhenol Catalyzed Enantioselective Mannich Reaction of 2 H-Azirines with Alkynyl Ketones

The enantioselective Mannich reaction of 2H-azirines with alkynyl ketones is achieved under Zn-ProPhenol catalysis, delivering various aziridines with vicinal tetrasubstituted stereocenters in high yields with excellent enantioselectivities. The bimetalli

Highly Enantioselective Iridium-Catalyzed Coupling Reaction of Vinyl Azides and Racemic Allylic Carbonates

The iridium-catalyzed enantioselective coupling reaction of vinyl azides and allylic electrophiles is presented and provides access to β-chiral carbonyl derivatives. Vinyl azides are used as acetamide enolate or acetonitrile carbanion surrogates, leading to γ,δ-unsaturated β-substituted amides as well as nitriles with excellent enantiomeric excess. These products are readily transformed into chiral N-containing building blocks and pharmaceuticals. A mechanism is proposed to rationalize the chemoselectivity of this coupling reaction.

Transformation of Alkynes into α- Or β-Difluorinated Alkyl Azides by an Efficient One-Pot Two-Step Procedure

Reported herein an unprecedented 1,2-azide migratory hydroazidation and subsequent gem-difluorination of alkynes accessing β-difluorinated alkyl azides. Importantly, functional group controlled 1,2-azide or 1,2-aryl migration was observed in the case of a

BF3·OEt2-Catalyzed Vinyl Azide Addition to in Situ Generated N-Acyl Iminium Salts: Synthesis of 3-Oxoisoindoline-1-acetamides

BF3·OEt2-catalyzed nucleophilic addition of vinyl azides to in situ generated N-acyl iminium salts obtained from 3-hydroxyisoindolinones is described in this article. The procedure is operationally simple, mild, additive, and metal-free. The reaction proceeds smoothly at ambient temperature with a wide range of 3-hydroxyisoindol-1-ones and vinyl azides to afford 3-oxoisoindoline-1-acetamides (32 examples) in high yields (up to 97%). Furthermore, the synthetic utility of this methodology is depicted by exploiting the reactivity of an amide functionality in the products.

Rhodium-Catalyzed Double Isocyanide Insertion via a Vinylcarbodiimide Intermediate for the Synthesis of 2H-Pyrrol-2-imines

2 H -Pyrrol-2-imine is an important structural motif exhibiting in biologically active compounds and natural products. An efficient rhodium-catalyzed one-pot reaction of one vinyl azide with sequentially with two different isocyanides is reported, which offers an alternative facile access to 3-amino-5-aryl-2 H -pyrrol-2-imines bearing various substitution on the nitrogens in good yields. An unstable vinylcarbodiimide is the key intermediate in this cascade reaction.

Switchable reactivity between vinyl azides and terminal alkyne by nano copper catalysis

A novel nano copper-catalyzed substrate-dependent chemodivergent transformation of vinyl azides with a terminal alkyne is disclosed. 2,5-Disubstituted pyrroles were selectively obtained in high yield with aryl alkynes and aliphatic alkynes, whereas 2,3,4-trisubstituted pyrroles were formed with silylated alkynes. This switchable method provides a controllable and facile access to both multisubstituted pyrrole scaffolds with high efficiency, excellent regioselectivity, and good functional group compatibility.

Electrochemical synthesis of enaminones: Via a decarboxylative coupling reaction

An environmentally benign and efficient electrochemical synthesis of enaminones via a decarboxylative coupling reaction of α-keto acids using n-Bu4NI as a redox catalyst and electrolyte under constant current electrolysis in an undivided cell is reported. A broad vinyl azide substrate scope and high functional group tolerance are observed. A gram-scale reaction further demonstrates the practicability of the protocol. The results of cyclic voltammetry and control experiments indicate that I2 is likely the active species to initiate the oxidative decarboxylation via an acyl hypoiodite intermediate.

Direct Assembly of 4-Substituted Quinolines with Vinyl Azides as a Dual Synthon via C=C and C-N Bond Cleavage

An unprecedented Zn-promoted selective cleavage of vinyl azides for the synthesis of 4-substituted quinolines is developed. In this conversion, vinyl azides function as a dual synthon via C=C and C-N bond cleavage with two C=C bonds and one C=N bond formation in a one-step manner. The reaction is appreciated for its readily accessible substrates, high step economy, mild conditions, and use of air as the sole oxidant.
