Synthesis of chiral germanium center enabled by poly-deborylative alkylation and desymmetrization

Nature Communications
Chiral germanium centers are historically undervalued due to their extremely limited synthetic accessibility. Although germanium shares similar chemical properties with silicon, synthesizing chiral germanium centers proves significantly more challenging.

Mechanistic Insights into Nickamine-catalyzed Alkyl-Alkyl Cross-coupling Reactions

CHIMIA, 2014
Within the last decades the transition metal-catalyzed cross-coupling of non-activated alkyl halides has significantly progressed. Within the context of alkyl-alkyl cross-coupling, first row transition metals spanning from iron, over cobalt ...

New insight in Hiyama cross-coupling reactions: Decarboxylative, denitrogenative and desulfidative couplings [PDF]

Chemical Review and Letters, 2018
In this mini-review, recent advances and developments in the decarboxylative, denitrogenative, and desulfidative Hiyama-type cross-coupling reaction from 2011 up present are studied.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Palladium(0) Deposited on PAMAM Dendrimers as a Catalyst for C–C Cross Coupling Reactions

Molecules, 2011
PAMAM dendrimers of generations G2–G3 as well as a partially substituted derivative of generation G4 and a low-molecular-weight tricyclic ligand 4 were used to bind Pd(0) nanoparticles. The obtained adducts were tested as catalysts for C–C cross-coupling

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Assembly of (hetero)aryl sulfilimines via copper-catalyzed enantioselective S-arylation of sulfenamides with (hetero)aryl Iodides

Nature Communications
The (hetero)aryl sulfoximines are important structures for developing bioactive molecules, whose synthesis relies on oxidation of (hetero)aryl sulfilimines. However, asymmetric approaches for assembling (hetero)aryl sulfilimines are still rare.
