  • Cross-linked polystyrene-TiCl4 complex as a reusable Lewis acid catalyst for solvent-free Knoevenagel condensations of 1,3-dicarbonyl compounds with aldehydes
    作者:Ali Rahmatpour、Niloofar Goodarzi
    DOI:10.1016/j.catcom.2018.11.001
    日期:2019.5
    in the range of (50–80 mesh size) were prepared by a new method, characterized and functionalized with titanium tetrachloride to afford the corresponding polystyrene‑titanium tetrachloride complex in one step reaction and characterized by FT-IR, UV, TGA, DSC, XRD, SEM, BET. This polymer metal complex (PS/TiCl4) was used as a heterogeneous, recoverable, reusable Lewis acid for solvent-free Knoevenagel
    通过一种新方法制备了平均粒径在(50-80目)范围内的交联聚苯乙烯共聚物珠,用四氯化钛对其进行了表征和功能化,从而在一步反应中得到了相应的聚苯乙烯-四氯化钛配合物,并对其进行了表征。通过FT-IR,UV,TGA,DSC,XRD,SEM,BET。该聚合物金属配合物(PS / TiCl 4)用作多相,可回收,可重复使用的路易斯酸,用于在绿色和温和条件下无溶剂的1,3-二酮与芳族醛的Knoevenagel缩合反应。发现反应速率随着交联百分比和共聚物珠粒的筛孔尺寸的增加而降低。该配合物在Knoevenagel反应中显示出良好的稳定性和催化活性。
  • A simple method for the preparation of functionalized trisubstituted alkenes and α,β,γ,δ-unsaturated carbonyl compounds by using natural amino acid l-tryptophan

    日期:2010.3
    reactive acetylacetone and ethyl acetoacetate. The reactions were carried out at room temperature and gave good yields. It is a convenient entry for preparation of functionalized trisubstituted alkenes and α,β,γ,δ-unsaturated carbonyl compounds.
    伯天然氨基酸1-色氨酸首次用作脂族,芳族,杂芳族和α,β-不饱和醛与反应性较低的乙酰丙酮和乙酰乙酸乙酯的Knoevenagel缩合反应的催化剂。反应在室温下进行,并得到良好的收率。这是制备官能化的三取代烯烃和α,β,γ,δ-不饱和羰基化合物的方便方法。
  • Enzyme catalytic promiscuity: The papain-catalyzed Knoevenagel reaction
    作者:Wen Hu、Zhi Guan、Xiang Deng、Yan-Hong He
    DOI:10.1016/j.biochi.2011.09.018
    日期:2012.3
    Knoevenagel reactions in DMSO/water. A wide range of aromatic, hetero-aromatic and α,β-unsaturated aldehydes could react with less active methylene compounds acetylacetone and ethyl acetoacetate. The products were obtained in moderate to excellent yields with Z/E selectivities of up to 100:0. This case of biocatalytic promiscuity not only widens the application of papain to new chemical transformations

    日期:2007.4
    er addition cascade has been developed whereby certain α,β-unsaturated carbonyl compounds, acting as organic Lewis acids, induce conversion of ortho esters into ketene acetals in situ. The ketene acetals then react with enones or acrylamides to yield derivatives of cyclic ortho esters.
