Organophotocatalytic dearomatization of indoles, pyrroles and benzo(thio)furans via a Giese-type transformation

open access: yesCommunications Chemistry, 2021
Dearomatisation of indoles allows efficient access to indolines, but often is incompatible with electron-withdrawing substituents. Here a photoredox Giese-type dearomatisation of indoles yields 2,3-disubstituted indolines bearing electron-withdrawing ...

Oxidative Dearomative Cross-Dehydrogenative Coupling of Indoles with Diverse C-H Nucleophiles: Efficient Approach to 2,2-Disubstituted Indolin-3-ones

open access: yesMolecules, 2020
The oxidative, dearomative cross-dehydrogenative coupling of indoles with various C-H nucleophiles is developed. This process features a broad substrate scope with respect to both indoles and nucleophiles, affording structurally diverse 2,2-disubstituted

Focus on chirality of HIV-​1 non-​nucleoside reverse transcriptase inhibitors [PDF]

open access: yes, 2016
Chiral HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of great interest since one enantiomer is often more potent than the corresponding counterpart against the HIV-1 wild type (WT) and the HIV-1 drug resistant mutant strains.
