  Synthesis of New Chiral Schiff Bases Containing Bromo- and Iodo-Functionalized Hydroxynaphthalene Frameworks

  摘要：

  [image omitted] Two series of chiral Schiff bases 3a-g and 4a-g containing bromo- and iodo-functionalized hydroxynaphthalene frameworks were conveniently prepared in acceptable to moderate yields by controlled halogenation of hydroxynaphthaldehyde and then condensation of the corresponding mono-, di-, and trihalohydroxynaphthaldehyde with the chiral amino alcohol. Except for 4d, the Schiff bases 3a-g, 4a-c, and 4e-g prepared in the present work have not been reported in literature so far, and they might be used as effective chiral inducers in some asymmetrically synthetic reactions.
