Chemistry in continuous-flow continues to attract attention from the community of synthetic
organic chemists due to its now well-recognized benefits including, inter alia, quick reaction …

N‐Heterocyclic carbene (NHC) catalysis is a by now consolidated organocatalytic platform
for a number of synthetic (asymmetric) transformations via diverse reaction modes/…

A strategy for the immobilization of the valuable triazolium carbene Rovis catalyst onto
polystyrene and silica supports is presented. Initially, the catalyst activity and recyclability were …

The flavonoid quercetin (3,3′,4′,5,7-pentahydroxyflavone) is widely distributed in plants,
foods, and beverages. This polyphenol compound exhibits varied biological actions such as …

Thiazolium salt pre-catalysts have been immobilized on silica and monolithic polystyrene
and their activity was tested under batch conditions in three model umpolung reactions, …

The application of the oxidative system composed of a heterogeneous triazolium pre-catalyst,
iron(II) phthalocyanine and air is described for the selective conversion of 5-…

N-Heterocyclic carbenes (NHCs) are now well-established organocatalysts for a large number
of asymmetric and non-asymmetric transformations. In the last 15 years, there has been …

A chiral NHC-catalyzed dearomatizing reaction of activated N-alkylpyridinium salts with
aliphatic aldehydes is described. The resulting acylated 1,4-dihydropyridines have been …

N-Heterocyclic carbene catalysis for the aerobic oxidation and esterification of aromatic
aldehydes was monitored by ESI-MS (MS/MS) and the key intermediates were intercepted …

Herein, we present the α-selective Giese reaction between pyranosyl/furanosyl bromides
and dehydroalanine analogues, which provides access to a library of highly valuable α-C-…
