  A new type of carboxypeptidase a inhibitors designed using an imidazole as a zinc coordinating ligand

  摘要：

  2-(4-Imidazoyl)hydrocinnamic acid (1) and its congeners (2-4) having different length of alkyl chain spacers between the imidazole ring and the a-carbon to the carboxylate of 1 have been designed, synthesized and evaluated as inhibitors for carboxypeptidase A to show that they are competitive inhibitors for the enzyme. Inhibitor 1 was most potent having the K-i value of 0.8 mu M. The present study demonstrates that imidazole ring is an effective zinc coordinating ligand that can be useful for the design of inhibitors for zinc proteases. (C) 1997 Elsevier Science Ltd.

  A method for increasing the rate of phosphine oxide reduction, preferably during a Wittig reaction comprising use of an acid additive is provided. A room temperature catalytic Wittig reaction (CWR) the rate of reduction of the phosphine oxide is increased due to the addition of the acid additive is described. Furthermore, the extension of the CWR to semi-stabilized and non-stabilized ylides has been accomplished by utilization of a masked base and/or ylide-tuning.

  The contra-thermodynamic isomerization of α- and β-substituted cinnamate derivatives catalyzed by the Cu(OAc)2/rac-BINAP complex under blue light irradiation is reported. The use of an oxazolidinone template, which favored the complexation of the copper catalyst to the substrate, allowed the E → Z isomerization of the catalytically formed chromophore under simple and robust reaction conditions in good

  developed the first catalytic (in phosphane) Wittig reaction (CWR). The utilization of an organosilane was pivotal for success as it allowed for the chemoselective reduction of a phosphane oxide. Protocol optimization evaluated the phosphane oxide precatalyst structure, loading, organosilane, temperature, solvent, and base. These studies demonstrated that to maintain viable catalytic performance it was

  我们开发了第一个催化（在膦中）维蒂希反应（CWR）。有机硅烷的使用对于成功至关重要，因为它可以使氧化膦的化学选择性还原。方案优化评估了氧化膦预催化剂的结构，负载量，有机硅烷，温度，溶剂和碱。这些研究表明，要保持可行的催化性能，必须使用1型环状氧化膦预催化剂。最初的底物研究以碳酸钠为碱，进一步的实验确定了N，N-二异丙基乙胺（DIPEA）作为可溶性替代品。DIPEA的使用提高了易用性，拓宽了底物范围，并降低了催化剂前负荷。优化的方案与烷基，芳基和杂环（呋喃基，吲哚基，吡啶基，吡咯基和噻吩基）醛兼容，可通过使用预催化剂以中等至高产率（60-96％）生产二取代和三取代的烯烃。负载量为4-10 mol％。动力学E / Z选择性通常为66:34；通过膦介导的异构化事件实现了对二取代的α，β-不饱和产物的完全E选择性。CWR用于合成54，这是抗阿尔茨海默病药物盐酸多奈哌齐的已知前体，以克为单位（12.2

  One ring no longer rules them all: Employment of 2.5–10 mol % of 4‐nitrobenzoic acid with phenylsilane led to the development of a room temperature catalytic Wittig reaction (see scheme). Moreover, these enhanced reduction conditions also facilitated the use of acyclic phosphine oxides as catalysts for the first time. A series of alkenes were produced in moderate to high yield and selectivity.

  一个环不再完全统治一切：用2.5-10 mol％的4-硝基苯甲酸与苯基硅烷一起使用导致了室温催化Wittig反应的发展（参见方案）。此外，这些增强的还原条件还促进了首次将无环氧化膦用作催化剂。以中等至高收率和选择性生产了一系列烯烃。
