  Dendrimer Poly(ethylenimine)s Linked to β-Cyclodextrin

  摘要：

  beta-Cyclodextrin was attached to two dendrimer poly(ethylenimine)s. The resulting cyclodextrin-containing dendrimers, CD-I and CD-II, can be considered either as dendrimers equipped with specific binding sites or as cyclodextrins containing amino groups around the cavities. Amines of CD-I and CD-II remarkably resisted protonation compared with those of the parent dendrimers. A compact conformation of CD-I or CD-II in which the dendrimer wraps itself around the cyclodextrin is proposed as a conformation consistent with the suppressed protonation. Esters containing t-butylphenyl groups were complexed by CD-I and CD-II and underwent fast deacylation. Kinetic data were obtained with several ester substrates, which revealed that two amino groups located in the vicinity of each cyclodextrin cavity of CD-I or CD-II participated as nucleophiles. In addition, optimum reactivity was attained when the spacer connecting the t-butylphenyl and the ester groups was -O-CH2- or -CH=CH-. Structures of the active sites for the accelerated deacylation of esters were elucidated on the basis of the kinetic data. (C) 1997 Academic Press.

Hammett plots for the reactions of 7a-i with the dissociated EtO – and ion-paired EtOK exhibit excellent linear correlations with X = 3.00 and 2.47, respectively. The reactions have been suggested to proceed through a stepwise mechanism in which departure of the leaving-group occurs after the RDS. The correlation of the kEtOK/kEtO ratio with the X constants

  比解离的 EtO - 更具反应性。7a-i 与解离的 EtO 和离子对 EtOK 反应的 Hammett 图表现出极好的线性相关性，分别与 X = 3.00 和 2.47。已建议反应通过逐步机制进行，其中离去基团的离开发生在 RDS 之后。kEtOK/kEtO 比率与 X 常数的相关性表现出极好的线性度，斜率为 –0.53。得出的结论是，离子对 EtOK 通过增加反应中心的亲电性而不是通过提高离去基团的离核性来催化反应。

  The rate of decomposition of a series of 4'-nitrophenyl 4-substituted benzoates has been measured at 341 K in benzene solutions of dodecylammonium propionate and butane-1,4-diamine bis-(dodecanoate). The bimolecular rate constant due to general acid-general base catalysis from the head-group components of the surfactants is dependent on the nature of the substituents, and the rate data have been correlated by Hammett σ and σ+, Tsuno-Yukawa, and Taft dual substituent parameter linear free energy relationships. The reactivity of the esters has also been compared with the 13C n.m.r. chemical shift of their carbonyl carbon atoms. The results are consistent with a mechanism involving a general-acid-catalysed aminolysis of the unprotonated ester.

  Amide bond synthesis is one of the most used reactions in medicinal chemistry. We report an amide bond formation reaction through deoxyfluorinated carboxylic acids under mild conditions using 2-pyridinesulfonyl fluoride. The reaction procedure has been used in a one-pot synthesis of amides and esters via in situ generation of acyl fluoride. This one-pot synthetic method provides easy access to amides
