  Synthesis of polyfunctional aliphatic carbonyl compounds under phase-transfer conditions

  摘要：

  We have studied mono- and dialkylation of malonic, acetoacetic, and cyanoacetic esters with esters of haloacetic and beta-halopropionic acids and addition of the CH acids mentioned and their analogs to methyl and ethyl acrylate under phase-transfer catalysis conditions, and also deethoxycarbonylation of the obtained products. We have demonstrated for the first time the possibility of Dieckmann cyclization under phase-transfer catalysis conditions and have developed a simple method for the synthesis of 2,3-di(ethoxycarbonyl)cyclopentanone, a key intermediate in the syntheis of deoxyprostaglandins, by cyclization of triethyl 1,2,4-butanetricarboxylate.

  The first example of a catalytic Michael addition reaction of non-activated aliphatic nitriles to α,β-unsaturated carbonyl compounds under mild, neutral conditions is reported. A new de-aromatized pyridine-based PNP pincer complex of the Earth-abundant, first-row transition metal manganese serves as the catalyst. The reaction tolerates a variety of nitriles and Michael acceptors with different steric

  报道了在温和、中性条件下非活化脂肪腈与 α,β-不饱和羰基化合物的催化迈克尔加成反应的第一个例子。地球丰富的第一排过渡金属锰的一种新的脱芳构化吡啶基 PNP 钳形配合物用作催化剂。该反应耐受具有不同空间特征和受体强度的各种腈和迈克尔受体。包括温度依赖性 NMR 光谱和 DFT 计算在内的机理研究表明，烷基腈的协同活化导致金属化腈亲核物质（α-氰基碳负离子类似物）的产生，是该机制的关键步骤。金属中心不直接参与催化键的形成，而是与配体合作，作为底物活化的模板。这种“模板催化”方法扩大了共轭加成反应的潜在供体范围。
