  摘要：

  The synthesis of the new chiral amidine (S,S)-N,N'-bis(1-phenylethyl)pivalamidine ((S)-HPETA) and its corresponding lithium salt (S)-LiPETA are reported, and their solid-state structures were investigated by single-crystal X-ray diffraction. Depending on the stoichiometric ratio and the ion radius of the rare-earth metal, the reaction of (S)-LiPETA with anhydrous lanthanide trihalides (Ln = Sc, Y, La, Nd, Sm, Lu) afforded mono-, bis-, and tris(amidinate) complexes. The mono(amidinate) compound [{(S)-PETA}LaI4Li2(thf)(4)], the bis(amidinate) complexes [({(S)-PETA}(2)Ln-mu-Cl)(n)] (Ln = Sc, Y, Nd, Sm, Lu), and the tris(amidinate) compound [{(S)-PETA}(3)Y] were isolated and structurally characterized by single-crystal X-ray diffraction. For the bis(amidinate) compounds, either monomeric or chloro-bridged dimeric structures were observed in the solid state. Furthermore, chiral bis(amidinate)-amido and-alkyl complexes [{(S)-PETA}(2)Ln{E(SiMe3)(2)}] (E = N, Ln = Y; E = CH, Ln = Sc, Y, Lu) were synthesized by salt metathesis and their catalytic activity and enantioselectivities were investigated in hydroamination/cyclization reactions. All of these compounds showed very good catalytic activity, and all of the investigated substrates were converted regiospecifically into their corresponding cyclic products under mild reaction conditions within good reaction times. The lutetium alkyl compound combined a high activity with good enantioselectivity.

  Synthesis of the title compound was accomplished via coupling of (S)-alaninyl-(S)-1-amino-3-methyl-4,5,6,7-tetrahydro-2H-3-benzazepin-2-one with the activated trimethylsilyl ester of (S)-2-trimethylsilyloxy-3-methylbutyric acid, followed by deprotection and crystallization in situ. The starting material was prepared by the condensation of (S)-1-amino-3-methyl-4,5,6,7-tetrahydro-2H-3-benzazepin-2-one with activated N-(2-methoxycarbonyl-1-methylvinyl)-(S)-alanine sodium salt in the form of the mixed carboxylic carbonic anhydride, followed by enamine hydrolysis using methanesulfonic acid.

  nucleophilic attack on the activated p-toluenesulfinic acid anhydride. Ultimately, the use of EDC-HCl to form the sulfinamides proved to be the best pathway for synthesis. Sulfinate esters were prepared by the process of activating p-toluenesulfinic acid with either cyanuric chloride, methanesulfonyl chloride, or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC-HCl).

  摘要 通过用氰尿酰氯，甲磺酰氯或1-乙基-3-（3-二甲基氨基丙基）碳二亚胺盐酸盐（EDC-HCl）活化对甲苯磺酸的方法制备亚磺酸酯。用氰尿酰氯活化对甲苯亚磺酸导致形成亚磺酸酯，并伴随着相应的砜的形成。使用甲磺酰氯通过甲磺酸对甲苯磺酸酐进行活化得到了亚磺酸酯和甲磺酸酯的混合物。碳二亚胺EDC的使用证明了目标亚磺酸酯的高度选择性形成可产生最佳结果。三甲基乙酸的使用-甲苯亚磺酸酐或氰尿酰氯实现亚磺酰胺的合成被证明是无效的，这是由于亲核对活化的对甲苯亚磺酸酐的化学选择性差。最终，证明使用EDC-HCl形成亚磺酰胺是合成的最佳途径。 通过用氰尿酰氯，甲磺酰氯或1-乙基-3-（3-二甲基氨基丙基）碳二亚胺盐酸盐（EDC-HCl）活化对甲苯磺酸的方法制备亚磺酸酯。用氰尿酰氯活化对甲苯亚磺酸导致形成亚磺酸酯，并伴随着相应的砜的形成。使用甲磺酰氯通过甲磺酸对甲苯磺酸酐进行活化得到了亚磺酸酯和甲磺酸酯的混合

  New chiral stationary phases (CSPs) based on chiral selectors covalently bound on a solid support were prepared. Chiral selectors were obtained from enantiomerically pure aromatic amines and 3,5-dinitrobenzoic acid and then linked to the support surface through the allylic double bond. Such obtained materials allow enantioseparation of racemates or enantiomerically enriched compounds. These chiral stationary phases can be used as fillings in chromatographic columns for enantiomer separation of naproxen type drugs and other similar non-steroidal anti-inflammatory drugs (NSAID) by means of high performance liquid chromatography on both the analytical and preparative scale.

  基于手性选择剂共价结合在固体支持上的新手性固定相（CSPs）已经制备。手性选择剂是从对映异构纯芳香胺和3,5-二硝基苯甲酸中获得的，然后通过烯丙基双键连接到支持表面。这样获得的材料可以用于拆分混合物或对映富集化合物的手性分离。这些手性固定相可以作为色谱柱中的填料，通过高效液相色谱在分析和制备尺度上对萘普生类药物和其他类似的非甾体类抗炎药物（NSAID）进行对映异构体分离。
