  Syntheses and properties of 5-substituted [n](2,4)pyridinophanes, model compounds of NAD(P)

  摘要：

  [n](2,4)Pyridinophane derivatives 5-8 having an ester or an amide group at the 5-position were synthesized by aza-Wittig reactions between beta-substituted vinyliminophosphoranes and cyclic alpha,beta-unsaturated ketones. [beta-(Methoxycarbonyl)vinyl]- (1), [beta-(N,N-tetramethylenecarbamoyl)vinyl]-(2), [beta-(N-benzylcarbamoyl)vinyl]-(3), and (beta-carbamoylvinyl)iminophosphorane (4) were synthesized from the corresponding vinyl azides and triphenylphosphine. The heptamethylene chains of 5-(methoxycarbonyl)[7](2,4)pyridinophane (5),5-(N,N-tetramethylenecarbamoyl)[7](2,4)pyridinophane (6), and 5-(N-benzylcarbamoyl)[7](2,4)pyridinophane (7) flipped with AG(double dagger) = 11.2 (T(c) = 10.3-degrees-C), 10.8 (T(c) = 0.2-degrees-C), and 10.5 kcal/mol (T(c) = -5.2-degrees-C), respectively. At lower temperatures, the three conformations of the heptamethylene bridge were frozen. Methylpyridinium iodides 10 (n = 7, 6, and 5) derived from 6 were reduced more easily [E1/2* (half height potential) = -1.65 V (n = 7); -1.63 V (n = 6); -1.29 V vs Ag/AgCl (n = 5)] than the reference compound, 2,4-diethyl-5-(N,N-tetramethylenecarbamoyl)pyridinium ion (11) [E1/2* = -1.82 V vs Ag/AgCl]. The reduced species dimerized quickly.

  N-aryl-and N-vinyldiaza-18-crown-6: Synthesis and complexing ability

  摘要：

  The nucleophilic aromatic and vinyl substitution using diaza-18-crown-6 as nucleophile afforded a number of its N,N'-diaryl-[aryl = 2,4-(NO2)(2)C6H3, 4-C5F4N, 4-CF3C6F4] and N,N'-dialkenyl-substituted derivatives [alkenyl = PhC(O)CH=CH, MeOCOCH=CH, (EtO2C)(2)C=C(Ph), etc.]. Arylation of diaza-18-crown-6 with nonactivated aryl bromides, such as 4-Me2NC6H4Br, 4-MeOC6H4Br, C6H5Br, and 4-CF3C6H4Br, was effected under catalysis by palladium complexes. N,N'-Diaryldiaza-18-crowns-6 having electron-acceptor substituents in the aromatic rings turned out to be incapable of fanning complexes with metal cations, while their analogs containing electron-donor para-methoxy and para-dimethylamino groups gave complexes with barium perchlorate.

The sequence of binding of 6-substituted pyrones is Cl greater than Br greater than H greater than CF3. 6-Chloro-2-pyranones bearing 4-phenyl or 3-(2-naphthylmethyl) substituents effected rapid inactivation of chymotrypsin, while those having 3-benzyl or 3-(1-naphthylmethyl) substituents gave slow inactivation and those with 3-phenyl or 3-alkyl
