cis-Myrtanethiol and a mixture of diastereoisomeric myrtanethiols were synthesized starting from (-)-β-pinene. Their oxidation with chlorine dioxide afforded a number of derivatives such as disulfides, S-thiol-sulfonates, sulfonyl chlorides, and sulfonic acids. The effects of reaction conditions (solvent nature, reactant molar ratio, reaction time, catalyst) on the yield and ratio of the products were studied. The corresponding sulfonyl chloride was obtained in quantitative yield by oxidation of thiol in the presence of vanadyl acetyl-acetonate, and optimal conditions were found for quantitative formation of myrtanesulfonic acid.

A straightforward methodology for the synthesis of anti-Markovnikov-type alcohols is presented. By using a specific cobalt triphos complex in the presence of Zn(OTf)2 as an additive, the hydrogenation of epoxides proceeds with high yields and selectivities. The described protocol shows a broad substrate scope, including multi-substituted internal and terminal epoxides, as well as a good functional-group tolerance. Various natural-product derivatives, including steroids, terpenoids, and sesquiterpenoids, gave access to the corresponding alcohols in moderate-to-excellent yields.
Visible-Light-Mediated Aerobic Oxidation of Organoboron Compounds Using in Situ Generated Hydrogen Peroxide

A simple and general visible-light-mediated oxidation of organoboron compounds has been developed with rose bengal as the photocatalyst, substoichiometric Et3N as the electron donor, as well as air as the oxidant. This mild and metal-free protocol shows a broad substrate scope and provides a wide range of aliphatic alcohols and phenols in moderate to excellent yields. Notably, the robustness of this method is demonstrated on the stereospecific aerobic oxidation of organoboron compounds.
