  钯催化的酯烯醇锌的 α-芳基化：反应条件和底物范围

  摘要：

  报道了通过芳基溴化物与酯的烯醇锌的钯催化偶联实现酯的分子间α-芳基化。已经开发出三种不同类型的烯醇锌的反应。使用分离的 Reformatsky 试剂、使用由 α-溴代酯和活化锌生成的 Reformatsky 试剂以及使用氯化锌猝灭酯的碱金属烯醇化物生成的锌烯醇化物，可以高产率进行酯的 α-芳基化。使用烯醇锌代替碱金属烯醇化物大大扩展了酯的芳基化范围。该反应在室温或 70 °C 下与含有氰基、硝基、酯、酮、氟、烯醇化氢、羟基或氨基官能团的溴代芳烃以及与溴代吡啶发生。酯的范围包括无环乙酸酯、丙酸酯和异丁酸酯、α-烷氧基酯和内酯。使用带有受阻五苯基二茂铁基二叔丁基膦(Q-phos)或高反应性二聚Pd(I)络合物{[P( t -Bu) 3 ]PdBr} 2 的催化剂进行酯的烯醇锌的芳基化。

  4-chloroaniline and its N,N-dimethyl derivative by photolysis in MeCN) added to enamines and gave the corresponding alpha-(4-aminophenyl) ketones in satisfactory yields. The yields of the same ketones were increased when silyl enol ethers were used in the place of enamines. The alpha-arylation of silyl enol ethers of aldehydes occurred with lower yields and only with the N,N-dimethyl derivative. The

  将4-氨基苯基阳离子（通常是通过在MeCN中通过光解通过4-氯苯胺及其N，N-二甲基衍生物进行光解而生成的）添加到烯胺中，并以令人满意的产率得到相应的α-（4-氨基苯基）酮。当使用甲硅烷基烯醇醚代替烯胺时，相同酮的产率增加。醛的甲硅烷基烯醇醚的α-芳基化收率较低，并且仅与N，N-二甲基衍生物发生。用乙烯酮甲硅烷基缩醛成功完成该步骤，一步即可得到良好产率的α-（4-氨基苯基）丙酸（乙酸）酯，这是制备止痛化合物的已知中间体。芳基阳离子与Danishefsky's二烯的反应得到芳基化的β-甲氧基烯酮。

• <i>Solar</i>ylations via 4-Aminophenyl Cations

  The application of the photo-S(N)1 reaction on sonic 4-chloroanilines was explored under solar irradiation in view of obtaining a convenient metal-free arylation method. Several reactions previously carried out by UV irradiation, as well as some new ones, where either a new trap (alpha-methylstyrene) ora new halide (N,N-dimethyl-4-fluoroaniline) were adopted, were studied under these conditions and found to occur conveniently. Furthermore, at least in some cases the halide starting concentration could be raised up to 0.2 M, the excess trapping agent reduced from 20:1 to 2.5:1, and the solvent replaced by more environmentally friendly (co)solvents including water. Under these improved conditions, the photoarylation was carried out in a gram scale by merely exposing the solution to solar irradiation. This process has a low impact on the environment and can be considered a serious competitor of metal-catalyzed arylations.
