Organosulfur Chemistry
Organosulfur compounds often engage in reactivity that defies the conventional intuition of organic chemists, making it good fun for the most adventurous of us - on top of being a fertile playground for new reactivity. Our group first became enamored by the magic of sulfur while studying the antioxidant activity of allicin, the origin of garlic’s characteristic odour. We have since pursued a variety of projects aimed at understanding the H-atom transfer activity of organosulfur compounds (some of which are among the most potent known) and radical substitution chemistry on polysulfide species, which has enabled synthetic method development and clarified the basis of their important antioxidant activity. We have also aimed to shed light on the various mechanisms by which thiols undergo oxidation, as this is key to the role of amino acid cysteine in protein structure/function and cell signaling.
