We synthesized a series of small symmetrical unsaturated disulfides by a multi-step reaction starting from organic alcohols, and we performed a preliminary test to evaluate the effect of these compounds on the viability of A549 lung cancer cells. The garlic-derived natural compound diallyl disulfide, known for its anticancer activity, was used as the lead compound in this study. We synthesized five

oxidation-labile groups such as free amines and alcohols. Combined experimental and computational studies reveal that the oxidation takes place via a polar two-electron process with concomitant and unexpected deoxygenation of the oxoammonium cation through homolysis of the weak N–O bond, differing from prototypical radical-based thiol couplings. This unusual consumption of the oxidant has significant
