Authors present herein an unprecedented diastereoconvergent synthesis of vicinal diamines from diols through an economical, redox-neutral process. Under cooperative ruthenium and Lewis acid catalysis, readily available anilines and 1,2-diols (as a mixture of diastereomers)couple to forge two C-N bonds in an efficient and diastereoselective fashion. By identifying an effective chiral iridium/phosphoric acid co-catalyzed procedure, the first enantioconvergent double amination of racemic 1,2-diols has also been achieved, resulting in a practical access to highly valuable enantioenriched vicinal diamines. And rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) was used in the research process.
rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas: 579-43-1 Category: alcohols-buliding-blocks) has been used in the preparation of trans-methyl meso-hydrobenzoin phosphite.
