  用于（反式）酯化的酰胺/两性两性离子催化剂：在生物柴油合成中的应用

  摘要：

  已经开发了一类基于酰胺阴离子/亚胺阳离子电荷对的两性离子有机催化剂。两性离子易于通过使氮丙啶与氨基吡啶反应来制备。它们催化地适用于酯交换和脱水酯化。机理研究表明，酰胺阴离子和亚胺阳离子在活化反应伙伴方面具有协同作用，亚胺阳离子部分通过非经典氢键与羰基底物相互作用。该反应可在温和条件下用于大规模合成生物柴油。

  An amide/iminium zwitterion catalyst has a catalyst pocket size that promotes transesterification and dehydrative esterification. The amide/iminium zwitterions are easily prepared by reacting aziridines with aminopyridines. The reaction can be applied a wide variety of esterification processes including the large-scale synthesis of biodiesel. The amide/iminium zwitterions allow the avoidance of strongly basic or acidic condition and avoidance of metal contamination in the products. Reactions are carried out at ambient or only modestly elevated temperatures. The amide/iminium zwitterion catalyst is easily recycled and reactions proceed in high to quantitative yields.

  Under moderate conditions aldoenol esters react with HAl(i-C4H9)2 to afford organoaluminium compounds, which upon hydrolysis yield 1,3-diols and on acetolysis form 1,3-diacetates. The diacetates are obtained in about 50% yields (based on enol ester) by distillation. Vinyl esters are converted to linear 1,3-diols or 1,3-diacetates, whereas enol acetates of higher aldehydes give 2-sec(or -tert)alkyl-1

  在中等条件下，醛烯醇酯与HAl（iC 4 H 9）2反应，得到有机铝化合物，其水解后生成1,3-二醇，并在乙酰分解时生成1,3-二乙酸酯。通过蒸馏以约50％的产率（基于烯醇酯）获得二乙酸酯。乙烯基酯被转化为直链的1,3-二醇或1,3-二乙酸酯，而高级醛的烯醇乙酸酯得到2-仲（或-叔）烷基-1,3-丁二醇或2-仲（或-叔）烷基-1，3-丁二醇二乙酸酯。
