Mechanistic details pertaining to the SmI2-H2O-mediated reduction and reductive coupling of 6-membered lactones, the first class of simple unactivated carboxylic acid derivatives that had long been thought to lie outside the reducing range of SmI2, were elucidated. Results provide new exptl. evidence that water enables the productive electron transfer from Sm(II) by stabilization of the radical anion intermediate rather than by solely promoting the first electron transfer as originally proposed. Notably, these studies suggest that all reactions involving the generation of ketyl-type radicals with SmI2 occur under a unified mechanism based on the thermodn. control of the second electron transfer step, thus providing a blueprint for the development of a broad range of novel chemoselective transformations via open-shell electron pathways. To complete the study, the researchers used rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .
Desymmetrization of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas:579-43-1 Related Products of 579-43-1) using chiral phosphine catalyst has been reported. Conversion of meso-hydrobenzoin to trans-stillbene oxide by treatment with an aryl sulfonyl chloride and aqueous sodium hydroxide has been reported.
