  Macrocyclic Amides Consisting of Helical Chiral 1,12-Dimethylbenzo[c]phenanthrene-5,8-dicarboxylate

  摘要：

  Helical chiral 1,12-dimethylbenzo[c]phenanthrene-5,8-dicarboxylic acid was synthesized and resolved in multigram quantities. The absolute configuration was determined by X-ray analysis of the bis(camphorsultamamide) derivative. A series of optically active macrocyclic amides consisting of the chiral unit and a dianiline spacer were synthesized by one-pot procedures, and their structures were compared by spectroscopy and X-ray crystallography. One of the cycloamides exhibited catalytic activity in the asymmetric addition of diethylzinc to aromatic aldehydes. N-Alkylated derivatives were also synthesized, which possessed folded structures distinct from those of the parent cyclic amides.

• Synthesis of Symmetrical Polynitrohelicenes and Their Chiral Recognition in the Charge Transfer Complexation

  former compound is converted to a 2,4,9,11-tetranitrohelicene. The tetranitrohelicenes form charge-transfer (CT) complexes with an electron-rich chiral diaminohelicene in solution. The studies on the chiral recognition reveal that the combinations of the same configuration of the helicenes form more stable complexes than that of the enantiomeric helicenes.

• Folding of dihelicenetriamines in water

  Diastereomeric triamines containing two helicene moieties, 1,12-dimethylbenzo[c]phenanthrene, were synthesized and found to form folded structures in the water. Such folding was not observed for an achiral compound possessing a naphthalene moiety. The (M,M)-dihelicenetriamine with matching configuration at the helicene moieties formed a more stable folded structure than the (P,M)-isomer containing two enantiomeric helicene groups. The most stable folded conformation was predicted by the Monte Carlo method with Amber force field of the dihelicenetriamine. (C) 2002 Elsevier Science Ltd. All rights reserved.
