  丁烯基铟与碘磷化合物自由基偶联合成含环丙烷磷化合物

  摘要：

  通过（环丙基甲基）锡烷和 InBr3 之间的金属转移反应制备的 α-或 β-碘代磷化合物（如碘膦酸酯、碘代膦氧化物和碘代硫代膦酸酯）与丁烯基的自由基偶联，得到相应的环丙基甲基化产物。自由基反应是由丁烯基铟产生的自由基物种在少量氧气的辅助下引发的。Butenylindium 不仅可用作环丙基甲基化试剂，还可用作自由基引发剂。为了成功偶联，使用了锡/铟金属转移，其中卤化锡副产物对反应系统呈惰性非常重要。此外，（环丙基甲基）锡烷和 InBr3 的金属转移提供了二丁烯基溴化铟作为单一产品，其与来自碘磷化合物的不稳定膦酰基物种顺利偶联。还应用了光化学方法（紫外线照射）并加速了偶联反应。产生的环丙基甲基化膦酸酯是 Horner-Wadsworth-Emmons 反应的良好中间体，并产生带有环丙烷部分的官能化烯烃。

  The invention deals with the method of the synthesis of dialkyl haloalkylphosphonates and dialkyl haloalkyloxyalkylphosphonates via a microwave-heated Michaelis-Arbuzov reaction of trialkylphosphites with dihaloalkanes or bis(haloalkyl)ethers in a closed vessel, during which the reaction mixture, containing a dihaloalkane or bis(haloalkyl)ether and a trialkylphosphite, is heated with microwave radiation with the standard frequency (2.45 GHz) to reach a reaction temperature which is specific for each individual halogen. In the subsequent reaction of the first dihaloalkane or bis(haloalkyl)ether halogen atom with trialkyl phosphite, the desired dialkyl haloalkylphosphonate or dialkyl haloalkyloxyalkylphosphonate is formed, but the reaction of its halogen atom with the so-far present trialkylphosphite, leading to the creation of the relevant bisphosphonate, no longer takes place. In the case of an inhomogeneous reaction mixture, also the desired product in the amount of 0.1-5 molar % is added to the reaction mixture for its homogenization, which homogenizes it and thus precludes its uncontrollable overheating. The entire process of synthesis is more effective, faster, less expensive and more environmentally friendly than the methods described so far in the literature. The possibility of performing the described procedure also in a continuous-flow microwave reactor allows industrial production with minimal demands on an optimization of the reaction conditions for larger quantities, eliminates some security risks, dramatically reduces the spatial demands in production and reduces the need for the usage of large-tonnage industrial reactors.

  该发明涉及通过微波加热的Michaelis-Arbuzov反应，在封闭容器中合成二烷基卤代烷基膦酸酯和二烷基卤代烷氧基烷基膦酸酯的方法。在反应过程中，包含二烷基卤代烷基膦酸酯和三烷基膦酸酯的反应混合物通过微波辐射加热至标准频率（2.45 GHz）的反应温度，该温度对于每种卤素都是特定的。在第一个二烷基卤代烷基膦酸酯或二烷基卤代烷氧基烷基膦酸酯的卤原子与三烷基膦酸酯的反应中，形成所需的二烷基卤代烷基膦酸酯或二烷基卤代烷氧基烷基膦酸酯，但其卤原子与迄今为止存在的三烷基膦酸酯的反应，导致相关双膦酸酯的生成，不再发生。在反应混合物不均匀的情况下，还向反应混合物中添加所需产品的0.1-5摩尔%的量以使其均匀化，从而防止其不受控制地过热。整个合成过程比文献中迄今描述的方法更有效、更快、更经济、更环保。在连续流动微波反应器中执行所述程序的可能性使得工业生产具有最小的反应条件优化要求，消除了一些安全风险，显著减少了生产中的空间需求，并减少了对大吨位工业反应器的使用需求。

  Chiral γ-phosphono-α-amino acids play a crucial role in inhibitors of natural enzymes, as well as agonists and antagonists of metabotropic glutamate receptors. In this paper, an efficient and general protocol for the construction of chiral γ-phosphono-α-amino acids via Pd-catalyzed AQ-directed C(sp3)–H alkylation of α-amino acid derivatives is developed. The reaction shows reactivity between methylene
