  Synthesis and Characterization of Upper and Lower Rim Functionalized [6]Cavitands

  摘要：

  A [6]cavitand has been selectively derivatized on both the lower and upper rims. On the lower rim, two out of six potential sites were oxidized to produce a 1,4 substituted [6]cavitand bisketone, which was converted to a corresponding diol as well as a bisacetate [6]cavitand. The crystal structures of the bisketone and the diol were solved. On the upper rim, all six ArCH3 groups were selectively brominated to ArCH2Br groups to produce the hexabromomethyl [6]cavitand, which was converted to the corresponding hexabenzylthiol and hexabenzylthioacetate [6]cavitands. The conformational properties of all compounds are discussed.
