Angewandte Chemie International Edition, Accepted Article.This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...

Angewandte Chemie International Edition, EarlyView.A sequential process combining hydrogenation and a subsequent stereomutation is presented for trans selective hydrogenation of quinolines using water as the hydrogen atom source. Mechanistic studies reveal that the hydrogenation proceeds through a cascade process comprising an initial cis selective photocatalytic hydrogenation of the heteroarene core ...

Angewandte Chemie International Edition, Accepted Article.Diastereoselective construction of organic scaffolds from simple and commercial materials is a powerful strategy in contemporary organic synthesis. Herein, we report a novel disconnection for the direct preparation of tetrahydrofurans (THF) and corresponding derivatives from acyl chlorides and alkenes using charge relocation. Newly synthesised Hantzsch
