Nitro-Grela-type complexes containing iodides – robust and selective catalysts for olefin metathesis under challenging conditions

Beilstein Journal of Organic Chemistry, 2015
Iodide-containing nitro-Grela-type catalysts have been synthesized and applied to ring closing metathesis (RCM) and cross metathesis (CM) reactions. These new catalysts have exhibited improved efficiency in the transformation of sterically, non-demanding

Palladium-catalysed formation of vicinal all-carbon quaternary centres via propargylation

Nature Communications, 2016
Formation of vicinal, quaternary stereocentres is challenging, but such products are commonly encountered in nature. Here, the authors report a palladium catalysed process to form vicinal quaternary carbons via propargylation, including in enantiopure ...

Antimalarial Potential of Synthetic Geraniol and Nerol Analogs

Journal of Chemistry
Drug resistance is a major threat to malaria control; therefore, new drugs are required to combat this parasitosis. To accelerate drug development, the exploration of natural compounds or the repositioning of drugs already employed for other diseases is ...

Entry to 2-aminoprolines via electrochemical decarboxylative amidation of N‑acetylamino malonic acid monoesters

Beilstein Journal of Organic Chemistry
The electrochemical synthesis of 2-aminoprolines based on anodic decarboxylation–intramolecular amidation of readily available N-acetylamino malonic acid monoesters is reported. The decarboxylative amidation under Hofer–Moest reaction conditions proceeds

Three-dimensional covalent organic frameworks with nia nets for efficient separation of benzene/cyclohexane mixtures

Nature Communications
The synthesis of three-dimensional covalent organic frameworks with highly connected building blocks presents a significant challenge. In this study, we report two 3D COFs with the nia topology, named JUC-641 and JUC-642, by introducing planar hexagonal ...
