The article was appeared in 《Organic Letters》. They have made some progress in their research.Electric Literature of C14H14O2 The article mentions the following:
A novel palladium-catalyzed alkene diacetoxylation with dioxygen (O2) as both the sole oxidant and oxygen source is developed, which was identified by 18O-isotope labeling studies. Control experiments suggested that bis(pinacolato)diboron (B2pin2) played a dominant intermediary role in the formation of a C-O bond. This method displayed good functional group tolerance with moderate to excellent yields and could be successfully applied to the late-stage modification of natural products. Furthermore, an atm. pressure of dioxygen enhances the practicability of the protocol. To complete the study, the researchers used rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .
rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas: 579-43-1 Electric Literature of C14H14O2) has been used in the preparation of trans-methyl meso-hydrobenzoin phosphite.
