Multiturn Hollow Helices: Synthesis and Folding of Long Aromatic Oligoamides

Aromatic oligoamides adopting helical conformations are synthesized by coupling carboxyl-terminated basic units having two, four, and eight residues to amine-terminated oligomer precursors. Coupling yields show no noticeable reduction with the size of the

Synthesis of crescent aromatic oligoamides

This article describes the synthetic procedures for the preparation of crescent (and helical) aromatic oligoamides developed in recent years in our laboratory. The large-scale preparation of a variety of monomers derived from various tetrasubstituted benzenes is presented. Three different strategies for constructing various oligomers consisting of meta- and meta/para-linked benzene residues are discussed. Factors affecting coupling efficiency and yields are analyzed. The developed synthetic methods have provided the basis for the preparation of longer oligomers and for the development of solid-phase synthesis.

N-(3-pyrrolidinyl) benzamide derivative

N-(3-Pyrrodinyl)benzamide derivatives represented by the following general formula (I) which have potent and selective antagonism against dopamine D3 and/or D4 receptor and are useful as a psychotropic, a schizophrenia-treating agent and the like, or a pharmaceutically acceptable salt thereof or a pharmaceutical preparation thereof.

Cerium(IV)-induced nitration of cinnamic acids. Novel remote electrophilic substitution

The treatment of (E)-3,4-dimethoxycinnamic acid with ceric amonium nitrate in trifluoroacetic acid afforded (E)1,2-dimethoxy-4-nitro-5-(2-nitroethenyl)benzene in 79percent yield.The unusual ipso substitution of the carboxylic acid moiety by a nitro functional center illustrated a new reaction manifold of cerium(IV).Six cinnamic acids were examined to ascertain the generality of the transformation.The bidentate nitrato structure of the metal salt is believed to account for the nitrating ability of this system.

Depsidone Synthesis. Part 21. A New Synthesis of Grisa-2',5'-diene-3,4'-diones

Treatment of suitably substituted methyl 2-phenoxybenzoates with titanium(IV) chloride and dry hydrogen chloride afforded grisa-2',5'-diene-3,4'-diones in high yield.The structures of these compounds followed from their thermal stability, their methanolysis to methyl 2-(4-hydroxyphenoxy)benzoates, and their reductive cleavage to 2,4'-dihydrobenzophenones.Treatment of the benzophenones with base gave xanthones.An attempt to synthesize dehydrogriseofulvin (1) by this method failed.
