Multi-membered O,N,S-heterocyclesR 0692 Macrocyclic Compounds from Benzenedithiols and Triazine: Modification of

Tetrathiacalix[4]arene. — The synthesis of the macrocyclic compounds (I) having benzenedithionate and triazine moieties is achieved by an efficient fragment coupling approach. In the solid state, they adopt 1,3-alternate conformations. Combination of two pairs of electron rich and electron poor units, and ortho-ortho and/or ortho-meta connections of sulfur atoms with aromatic carbons are novel features of the macrocy-cles. — (ALAM, A.; YAMAGUCHI, M.; YAMAMOTO, T.; NAKAJO, S.; OGAWA, S.; SATO*, R.; J.
