Direct asymmetric N-propargylation of indoles and carbazoles catalyzed by lithium SPINOL phosphate

open access: yesNature Communications, 2020
Asymmetric functionalization of N–H bonds constitutes an important but less developed class of reactions. Here, the authors report the asymmetric direct N-propargylation of indoles and carbazoles with a lithium SPINOL phosphate as the chiral catalyst and

Catalyst-driven scaffold diversity : selective synthesis of spirocycles, carbazoles and quinolines from indolyl ynones [PDF]

open access: yesChemistry, 2016
Medicinally relevant spirocyclic indolenines, carbazoles and quinolines can each be directly synthesised selectively from common indolyl ynone starting materials by catalyst variation.

Gold-Catalyzed Synthesis of 1-(Indol-3-yl)carbazoles: Selective 1,2-Alkyl vs 1,2-Vinyl Migration [PDF]

open access: yesOrganic Letters, 2017
Gold(III)-catalyzed cycloisomerization of α-bis(indol-3-yl)methyl alkynols selectively affords 1-(indol-3-yl)carbazoles, in a transformation that takes place through a selective 1,2-alkyl vs 1,2-vinyl migration step in the vinyl-gold intermediate ...

Industrial source identification of polyhalogenated carbazoles and preliminary assessment of their global emissions

open access: yesNature Communications, 2023
Polyhalogenated carbazoles (PHCZs) are emerging global pollutants found in environmental matrices, e.g., 3000 tonnes of PHCZs have been detected in the sediments of the Great Lakes.

An Update of Carbazole Treatment Strategies for COVID-19 Infection

open access: yesApplied Sciences, 2023
The Coronavirus disease 2019 (COVID-19) outbreak was declared by the World Health Organization (WHO) in March 2020 to be a pandemic and many drugs used at the beginning proved useless in fighting the infection. Lately, there has been approval of some new

Carbazole Substituted BODIPYs [PDF]

open access: yesFrontiers in Chemistry, 2019
Difluoroboron-dipyrromethenes (BODIPYs) are highly popular fluorescent dyes with applications as NIR probes for bioimaging, fluorescent tags/sensors and as photosensitizers in cancer therapy and organic photovoltaics. This review concentrates on the synthesis and spectral properties of BODIPY dyes conjugated with carbazole heterocycle. The carbazole is
