  amine-salicylamide derived from chiral trans-cyclohexane-1,2-diamine was used as an organocatalyst for the enantioselective conjugate addition of aldehydes, mainly α,α-disubstituted to N-substituted maleimides. The reaction was performed in toluene as a solvent at room temperature. The corresponding enantioenriched adducts were obtained with high yields and enantioselectivities up to 94%.

  Three enantiopure fluorous thioureas featuring a free –NH2 group were synthesized by direct addition of aromatic isothiocyanates bearing a single n-C8F17 substituent in the ortho, meta and para position, respectively, to enantiopure (1R,2R)-1,2-diaminocyclohexane. The catalytic behavior of these bifunctional molecules was assessed in representative Michael-type reactions. The three fluorous thioureas performed similarly in all the reactions tested, thus showing that the position of the fluorous ponytail does not have a major influence on the catalytic behavior of this class of compounds. In particular, excellent enantioselectivities (up to 99% ee) and yields (up to 98%) were obtained for the addition of aliphatic aldehydes to maleimides to give α-substituted succinimides. Recyclability of these primary amine-based thioureas was found to be limited by the concurrent formation of imine-derivatives during the catalytic process, leading to a structural modification of the organic catalyst.

  通过将分别在正位、偏位和对位具有单个 n-C8F17 取代基的芳香族异硫氰酸酯直接加到对映体 (1R,2R)-1,2-二氨基环己烷上，合成了三种具有游离 -NH2 基团的对映体荧光硫脲。在具有代表性的迈克尔型反应中，对这些双功能分子的催化行为进行了评估。这三种有荧光的硫脲类化合物在所有测试反应中的表现相似，从而表明荧光马尾的位置对这类化合物的催化行为没有重大影响。特别是在脂肪醛与马来酰亚胺的加成反应中，获得了极好的对映选择性（ee高达 99%）和收率（高达 98%），从而得到了 α-取代的琥珀酰亚胺。研究发现，这些伯胺基硫脲的可回收性受到催化过程中同时形成的亚胺衍生物的限制，从而导致有机催化剂结构的改变。

  羰基化合物与N-取代马来酰亚胺的不对称迈克尔加成是获得光学纯琥珀酰亚胺的重要方法，琥珀酰亚胺是重要的手性精细化工中间体。环保和可持续的程序需要使用从天然手性来源和廉价助剂获得的多相、可回收催化剂。在这里，我们报告了使用氨基酸（如L-苯丙氨酸和粘土矿物或氧化铝）原位形成的手性无机-有机杂化催化剂的应用，这些催化剂在将醛添加到种类繁多的N-取代的马来酰亚胺。检查表明可回收的固体杂化材料表面发生了不对称反应。通过热重分析、XRD、FT-IR和拉曼光谱、SEM和吸附实验对催化材料进行了检测。这些方法的结果表明，氨基酸以表面微晶的形式沉积或嵌入层状阳离子交换剂中，两者都作为手性源的供应，而反应由吸附在表面上的手性化合物催化。该催化体系用于方便地制备克级手性琥珀酰亚胺，易于通过结晶纯化。因此，这些手性杂化材料是方便的非均相催化剂，用于使用天然手性源获得高光学纯度的有价值的化合物，
