Bidirectional Metalation of Hydrobenzoin: Direct Access to New Chiral Ligands and Auxiliaries
摘要:
A bidirectional ortho metalation of the readily available chiral diol hydrobenzoin has been developed that provides direct access to new ortho-functionalized hydrobenzoin derivatives. This one-pot procedure should broaden the utility of hydrobenzoin as an auxiliary and ligand in asymmetric synthesis.
