  • Arene-metal complexes: Preparation and reactions of h6-arene-Cr(CO)2(diphos) and analogs
    作者:M.F. Semmelhack、Walter Seufert、L. Keller

    h6-arenetricarbonylchromium(0) complexes results in replacement of one CO by diphos to give h6-arene(diphos)dicarbonylchromium(0) (e.g., complex 4) and μ-diphosbis(h6-arene)tetracarbonyldichromium(0). Comparison of rate of arene exchange for h6-benzenetricarbonylchromium, h6-benzene(triphenylphosphine)dicarbonylchromium, and complex 4 showed that: (1) replacement of CO by a phosphine retards arene exchange

    This invention concerns a new process of preparing optically active .alpha.-arylalkanoic acids and their precursors. These .alpha.-arylalkanoic acids, esters, amides, nitriles, oxazolines and metal salts are stereoselectively prepared by forming the metal or metal halide of the corresponding acid, ester, amide, oxazoline, nitrile, or metal salt and treating the compound so prepared with an aryl halide in the presence of a chiral (optically active) transition metal catalyst of the formula (LL*)QZT wherein Q is a transition metal selected from palladium and nickel; Z and T are independently halogen; and LL* is a chiral tertiary diphosphine compound capable of acting as a bidentate ligand with Q to form a 5-membered ring, optionally in the presence of a dipolar aprotic solvent or mixtures thereof, for a time sufficient to form the corresponding optically active .alpha.-arylalkanoic acid, ester, amide, nitrile, oxazoline or metal salt, and optionally concomitantly or sequentially hydrolyzing any ester, amide, nitrile, oxazoline or metal salt formed to the corresponding optically active .alpha.-arylalkanoic acid. The process optionally further includes removal of halogen atom from the aromatic portion of the .alpha.-arylalkanoic acid. The process optionally includes subsequent formation of the pharmaceutically acceptable salts and esters of the optionally active .alpha.-arylalkanoic acid. This is a simple process for the preparation of the described optically active .alpha.-arylalkanoic acids. These compounds are useful as pharmaceutical (e.g., anti-inflammatory) agents.
    这项发明涉及一种制备光学活性α-芳基烷酸及其前体的新工艺。这些α-芳基烷酸、酯、酰胺、腈、噁唑啉和属盐通过形成相应酸、酯、酰胺、噁唑啉、腈或属盐的属或属卤化物,并在手性(光学活性)过渡属催化剂的存在下,将所制备的化合物与芳基卤化物反应,选择性地制备。该过渡属催化剂的化学式为(LL*)QZT,其中Q是从中选择的过渡属;Z和T分别是卤素;LL*是一种手性三膦化合物,能够与Q形成5元环的双齿配体,可选地在二极性无氢溶剂或其混合物的存在下,在足够时间内形成相应的光学活性α-芳基烷酸、酯、酰胺、腈、噁唑啉或属盐,并可选择性地同时或顺序解任何形成的酯、酰胺、腈、噁唑啉或属盐,形成相应的光学活性α-芳基烷酸。该工艺可选地进一步包括从α-芳基烷酸的芳香部分去除卤素原子。该工艺可选地包括随后形成药用可接受的盐和酯的可选择性活性α-芳基烷酸。这是一种简单的制备所述光学活性α-芳基烷酸的工艺。这些化合物可用作药用剂(例如,抗炎药物)。

    −CH(CH3)CN to an arenechromium tricarbonyl is studied. The major product obtained after oxidative removal of the metal corresponds to nucleophilic addition on an arene carbon atom which is in an eclipsed position with respect to the carbonyl group of the Cr(CO)3 unit of the most stable conformer. The synthesis of the corresponding acid represents an example of arenechromium tricarbonyl chemistry applied to synthesis
    研究了在-CH(CH 3)CN与芳基三羰基的加成反应中获得的产物分布。氧化除去属后获得的主要产物对应于芳烃碳原子上的亲核加成,该芳烃碳原子相对于最稳定构象异构体的Cr(CO)3单元的羰基处于偏位。相应酸的合成代表了用于合成具有药物特性的有机化合物的三羰基苯甲酸化学的一个实例,而传统方法只能通过多步法来合成。
