Abstract: Oxidation of lignin through selective C-C bond cleavage via metal-free and mild strategies is promising but challenging to value-added aromatics. We discovered that cation of ionic liquids (ILs) could effectively catalyze this kind of strong… read more here.

DOI: 10.1021/jacs.0c05042
Abstract: We report a concise, stereocontrolled synthesis of the neurotoxic sesquiterpenoid (-)-picrotoxinin (1, PXN). The brevity of the route is due to regio- and stereoselective formation of the [4.3.0] bicyclic core by incorporation of a symmetrizing… read more here.
