  Orthocyclophanes. 2. Starands, a new family of macrocycles of spirobicyclic polyketals with a 2n-crown-n moiety

  摘要：

  Synthesis and functionalization of higher members of the [1n]orthocyclophanes, or [1n]OCPs, have been investigated. Oxidation of the benzylic methylenes in [1n]OCPs gave the polyoxo derivatives. Exhaustive oxidation of all methylenes in even-numbered [1n]OCPs gave rearranged isomers of the cyclopolyketal structure instead of the corresponding polyoxo derivatives. We propose the class name ''starands'' for this new family of crown compounds for their star-shaped crown ether structure. Detailed synthesis and characterization of two starands are described.
