2. Iridium-Catalyzed C−H Activation Methods for Late-Stage Functionalization of Pharmaceuticals
Abstract : C-H activations have over the recent decades risen from a mere curiosity to a viable synthetic strategy. However, challenges in terms of accessible transformations, selectivity and functional group tolerance limit the widespread applicability of this approach. READ MORE

3. Amine Transaminases in Multi-Step One-Pot Reactions
Abstract : Amine transaminases are enzymes that catalyze the mild and selective formation of primary amines, which are useful building blocks for biologically active compounds and natural products. In order to make the production of these kinds of compounds more efficient from both a practical and an environmental point of view, amine transaminases were incorporated into multi-step one-pot reactions.

4. Valorisation of Renewable Building Blocks via Transition Metal Catalysis – Glycerol- and Amino Acid Derived Compounds in Hydrogen Borrowing and RuAAC Reactions
Abstract : To a large extent, organic building blocks are today obtained from petroleum-based products. From an environmental point of view, biomass-derived compounds are more sustainable alternatives to such oil-derived molecules. The 12 principles of green chemistry describe how chemical processes can be improved in terms of sustainability. READ MORE
