The synthesis and conformation of oxygenated trianglimine macrocycles

The synthesis of series of D2h and C2v symmetric oxygenated aromatic dicarboxaldehydes, using dilithiation methodology, is described along with their reactivity in the [3 + 3] cyclocondensation reaction with (1R,2R)-diaminocyclohexane to give oxygenated trianglimine macrocycles. Macrocycles derived from C2v symmetric dialdehydes give macrocycles with a stereogenic aromatic plane with complete diastereocontrol, as a mixture of retainers.

Preparation and nonlinear optics of monodisperse oligo(1,4-phenyleneethynylene)s

Oligo(1,4-phenyleneethynylene)s 1a-e, with solubilizing propoxy side chains, were prepared by use of Hagihara-Sonogashira coupling reactions. The synthetic strategy was based on a building block system and on the use of trimethylsilyl and triisopropylsily
