The nucleophilic small molecule catalyst (−)-tetramisole was found to catalyze the kineticresolution of monofunctional secondaryalcohols via enantioselective silylation. Optimization of this new methodology allows for selectivity factors up to 25 utilizing commercially available reagents and mild reaction conditions.

heteroatom (nitrogen, oxygen, and sulfur) on the course of the palladium-catalysed intramolecular reactions of aryliodides and aldehydes having heteroatom-containing tethers has been explored by an extensive experimental–computational (DFT) study. Two series of substrates were considered, namely aldehydes bearing either the α-(2-iodobenzylheteroatom) or β-(2-iodophenylheteroatom) moieties. While some

studies revealed that they were mixed inhibitors. Insights into their mechanism of action were obtained through molecular docking and STD-NMR experiments, and the most active examples showed excellent drug-likeness and pharmacological properties predicted using Swiss-ADME. We also prepared a set of propargyl gem-dimethylchromanamines, for monoamineoxidase (MAO) inhibition but they were only moderately
