  An Access to erythro-Diols via Sharpless's Asymmetric Dihydroxylation Reaction

  摘要：

  A method has been developed to access erythro-2,3-diols via Sharpless's asymmetric dihydroxylation reaction. Thus, a TBDMS-protected (E)-allylic alcohol is dihydroxylated and the resulting threo-2,3-diol is converted to the cyclic sulfate. Upon desilylation, this compound undergoes a Payne-type rearrangement. Nucleophilic epoxide-opening then provides an erythro-2,3-diol. The conversions from the cyclic sulfate to the diol product are performed in a single reaction vessel. Due to the irreversible nature of the Payne-type rearrangement, this process is easy to perform and completely regioselective independent of the substrate structures. Also, being performed in THF, the process is compatible with a variety of nucleophiles, including thiolates, N--(3), (OAc)-O--, (CN)-C--, halides as well as carbon nucleophiles and hydride.

  摘要：

  Asymmetric dihydroxylation provides an easy access to tetrose: threose directly from the (E)-olefin 1, and erythrose via an irreversible Payne-type rearrangement - opening process of the threitol cyclic sulfate 5.

  The ring-opening reaction of epoxy sulfides with phenylboronic acid in benzene has been demonstrated to occur stereospecifically via episulfonium ions, i.e., with double inversion of configuration, giving rise to phenylboronic esters of 2,3-diols in quantitative yields.
