The synthesis of new optically pure diselenides has been realized in one pot, starting from 2, 2′- diselenobisbenzoic acid and naturally occurring chiral alcohols through a Mitsunobu reaction.They were used to promote electrophilic methoxyselenenylation of styrene, affording moderate to poor diasteroselectivity. The reason of the low stereoselection has been investigated on the basis of 77Se - NMR experiments, evidencing an alternate double coordination with the oxygens of the carboxylic moiety. Some theoretical implications of these interactions in the GPx – like activity of the diselenides will be discussed.

Oxidation reactions are fundamental and useful chemical transformations, especially for industries. However, the use of heavy metals or stoichiometric organic agents as common oxidants are nowadays rejected, preferring greener and economical procedures. Here, we propose a simple and sustainable method to oxidize aldehydes at room temperature using, in water, hydrogen peroxide as oxidant and PhSe)2 as catalyst which is a not expensive and commercially available organoselenium reagent. Differently substituted aromatic and aliphatic aldehydes underwent the oxidation in good yields. In the presence of an alcoholic medium, the same substrates can be directly converted into the corresponding esters using the same reaction conditions. In order to avoid the side formation of carboxylic acid the reactions were heated at 50°C in acidic conditions. We also demonstrated that in the same conditions carboxylic acid was not transformed into the corresponding ester. This latter evidences suggest that the oxidation occurred on the hydrated aldehydes or on the hemiacetal in the presence of water and alcohols respectively . Aknowledgment: Technical support of Mr. Lorenzo Bettona from I.T.T.S. "Alessandro Volta", Perugia has been particularly appreciated.

The selenium catalyzed oxidation by hydrogen peroxides was achieved for the synthesis of epoxides1. Our group recently developed the stereoselective synthesis of anti-1,2-diols passing through an epoxide intermediate2 and involving a perselenenic acid as actual catalyst of the whole process. Here we report the cyclofunctionalization of beta,gamma- and gamma,delta unsaturated acids, and alcohols. The stereoselectivity has been investigated starting from substrates containing additional chiral center in the α position as well as optically pure catalysts. All the reactions were carried out using 4 equivalents of hydrogen peroxides (30%) and diselenides as precatalysts without any organic solvents. High regio- and stereo-selectivity were obtained for almost all the substrates but unfortunately using optically pure diselenides only moderated enantiomeric excesses were obtained. The reaction conditions present important eco-friendly features (on water conditions, room temperature and pressure), generally affording high yields. - References - 1) Garcìa-Marìn,H; van der Toorn, J.
