Summary: The rising costs of pharmaceutical research are currently limiting the productivity of drug discovery and development, but can potentially be reduced through miniaturization of compound synthesis and screening. In this study, the influential palladium-catalyzed Suzuki-Miyaura reaction is successfully implemented at the nanoliter scale on droplet microarrays for the synthesis of an 800-compound library of biphenyls. The synthesis of these compounds requires minimal reagents and solvent volume, and the obtained compounds can be purified and cleaved from excess reactants and catalyst. This novel approach expands the capabilities of droplet microarrays for miniaturized high-throughput chemical synthesis and opens up possibilities for future synthesis and screening of chemical compounds in a single platform.

Summary: This study investigates the catalytic activity of Pd (II) complexes of phosphino-benzaldoxime ligands in Suzuki-Miyaura coupling reactions. The results show that reducing the amount of catalyst leads to an increase in catalytic activity, and it is found that palladium nanoparticles formed in the reaction medium are responsible for this activity. This study contributes to the debate over whether the catalytic activity of phosphine-palladium complexes in SMC reactions results from a homogeneous or heterogeneous pathway.

Summary: The diastereoselective synthesis of densely functionalized tetrasubstituted (E)-monofluoroalkenes via Pd(0)-catalyzed base-free Suzuki-Miyaura crosscouplings offers a significant method for producing pharmaceutically relevant compounds. Computational studies support the reaction design, revealing an intriguing mechanism of C-F bond activation leading to complete control of stereoselectivity. This method does not require extraneous base assistance, making it a powerful tool for stereocontrolled synthesis of monofluoroalkenes.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
