  大环二酰胺的高效合成

  摘要：

  已经制备了一些新的大环二苯并三恶二酰胺，三苯并三恶二酰胺和四苯并六草酸酯四酰胺（1–9）。在大环化步骤中，通过使二羧酸二氯化物（13）与适当的二胺在CH 2 Cl 2中反应，得到化合物（2–9）。环化不需要高稀释技术或模板效果，并能以80％至95％的高收率提供预期的双内酰胺。然而，二胺（14a）与二羧酸二氯化物（13）在高稀释条件下的反应以中等收率产生了二内酰胺（2）和四内酰胺（1）的混合物。

  Some new macrocyclic dibenzotrioxadiamides, tribenzotrioxadiamides and tetrabenzohexaoxatetraamide (1–9) have been prepared. Compounds (2–9) were obtained in the macrocyclization step by reacting the dicarboxylic acid dichloride (13) with appropriate diamine in CH2Cl2. The cyclization does not require high dilution techniques or template effect and provides the expected dilactams in high yields, ranging

  A number of macrocyclic diamides have been synthesized from the reaction of a diacid dicarboxylic dichloride with primary diamino compound in the presence of magnesium oxide-silica gel at room temperature in good yields. Using urea and thiourea as well as diamines to produce the corresponding macrocycles in the range of 52–56% yields are also included in this paper. One of the major advantages of this

• Crown Ethers as New Catalysts in the Highly Regioselective Halogenative Cleavage of Epoxides with Elemental Halogen

  The regioselective ring opening halogenation of some epoxides using elemental iodine and bromine in the presence of a series of new synthetic macrocycle diamides and also dibenzo-18-crown -6, 18-crown-6, and aza-18-crown-6 has been studied. The epoxides were subject to cleavage by elemental halogen (I-2 and Br-2) in the presence of these catalysts under mild reaction conditions in various aprotic solvents. In this study, reagents and conditions have been discovered with which the individual halohydrins can be synthesized in high yield and with more than 95% regioselectivity. The results can be discussed in terms of a four-step mechanism: (1) formation of a charge-transfer complex between catalyst and halogen, (2) release of halogen nucleophile from the complex, (3) reaction of the active nucleophile at the less sterically-hindered site in the epoxide, and (4) regeneration of catalyst. The major advantages of this method are high regioselectivity, simple regeneration of catalyst and its reuse through several cycles without a decrease in activity, and ease of workup of the reaction.

  New fluorescent reagents, 2,2'-[oxybis(3-oxapentamethyleneoxy)]-bis[N(1-pyrenylmethyl)benzamide)] (4) and its analogues (2, 3, and 5) which have two pyrenes at the both terminals of polyoxyethylene compounds, were synthesized, and their complexation behavior with alkaline earth cations was investigated by fluorescence spectrometry, fluorescence lifetimes, and H-1 NMR spectrometry. These reagents (3-5) showed strong intramolecular excimer emissions around at 480 nm in the fluorescence spectra. On the complexation with alkaline earth metal cations, the increase of monomer emission around at 400 nm accompanied by the disappearance of intramolecular excimer emission of free reagents was observed. These reagents formed a 1:1 complex, and the order of complex formation constants was Ca2+ congruent to Sr2+ > Ba2+ > Mg2+ > Li+ for all reagents. H-1 NMR spectra of these complexes with alkaline earth cations suggested the helical structures of the complexes. Fluorescence spectral changes at the formation of complexes depended on the chain length of the oxyethylene moiety and metal cations. In all cases, the formation of helical structures at the complexation was supported by the H-1 NMR spectra.
