Synthesis and functionalization of higher members of the n>orthocyclophanes, or n>OCPs, have been investigated.Oxidation of the benzylic methylenes in n>OCPs gave the polyoxo derivatives.Exhaustive oxidation of all methylenes in even-numbered n>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.
