2018-04-15

A new family of photoactivatable HNO donors of general structure RSO2NHO‐PT [where PT represents the (3‐hydroxy‐2‐naphthalenyl)methyl (3,2‐HMN) phototrigger] has been developed, which rapidly releases HNO. Photogeneration of HNO was demonstrated using the vit...

Catalytic C‐Alkylation of Pyrroles with Primary Alcohols: Hans Fischer's Alkali and a New Method with Iridium P,N,P‐Pincer Complexes

2018-03-30

Hydrogen‐autotransfer alkylation (HAT or “borrowing‐hydrogen” alkylation) of heteroaromatic compounds has been studied with a range of substrates recently, but pyrroles have been largely absent from such studies. The conditions for HAT alkylations of pyrroles...

Fluorine‐Containing Functionalized Cyclopentene Scaffolds Through Ring Contraction and Deoxofluorination of Various Substituted Cyclohexenes

10.1002/ejoc.201800057

2018-03-30

The fluorination of some highly‐functionalized cyclopentene derivatives, obtained from various substituted cyclohexenes through a ring‐opening/ring‐contraction procedure, has been investigated. The transformations were found to be highly substrate dependent, ...

Verdazyl Radical Building Blocks: Synthesis, Structure, and Sonogashira Cross‐Coupling Reactions

2018-03-30

A general and effective method for the synthesis of 3‐phenylveradzyl radicals bearing a variety of iodophenyl substituents has been developed. The synthesized radicals have been characterized by ESR, UV/Vis spectroscopy, and cyclic voltammetry. Structures of ...

Iron‐Catalyzed Sulfur‐Promoted Decyanative Redox Condensation of o‐Nitrophenols and Arylacetonitriles: An Unprecedented Route to 2‐Arylbenzoxazoles

10.1002/ejoc.201701607

2018-03-30

Elemental sulfur in the presence of a catalytic amount of FeCl2·4H2O was found to be highly efficient for the promotion of decyanative redox condensation reactions of o‐nitrophenols with arylacetonitriles, to give a wide range of 2‐arylbenzoxazoles. The utili...

Nucleobases Having M–C Bonds: An Emerging Bio‐Organometallic Field

10.1002/ejoc.201800135

2018-03-24

The combination of nucleobases with metals has been a subject of study for the last half century. The understanding of some biological processes and, especially, of the mode of action of metal‐based antitumor drugs, has focused the advances in the field on me...

N‐Acyl‐Glutarimides: Privileged Scaffolds in Amide N–C Bond Cross‐Coupling

10.1002/ejoc.201800109

2018-03-24

In this Microreview, we describe the recent exciting developments in the burgeoning area of amide N–C cross‐coupling enabled by amide bond twist of N‐acyl‐glutarimides. Since the initial reports in 2015, these amides have been demonstrated to be by far the mo...

Green/Yellow‐emitting Conjugated Heterocyclic Fluorophores for Luminescent Solar Concentrators

In this study, we report on the synthesis of new organic fluorophores containing either the benzo[1,2‐d:4,5‐d']bisthiazole or the dithieno[3,2‐b:2',3'‐d]silole heterocyclic unit, and on their application for the fabrication of luminescent solar concentrators ...

THE WONDERFUL CHEMISTRY OF TRIFLUOROMETHYL α‐HALOALKENYL KETONES

10.1002/ejoc.201800194

2018-03-15

Fluorinated α‐bromoenones have received considerable attention in recent decade. Their ability to react in 1.2‐ and 1.4‐addition mode as well as the presence of bromine makes them valuable fluorinated building blocks in organic synthesis. This review is focus...
