Non symmetric sec,sec 1.2-diols and their O-isopropylidene derivatives undergo a regioselectiveoxidation by dimethyldioxirane depending on the electronic effects of the substituents. These results support previous views about the concerted -insertion mechanism via a polar transition state.
The OsCl3-catalyzed oxidation of alkenes with peracetic acid at room temperature gives the corresponding α-ketols, which are important building units for synthesis of biological active compounds.
