    摘要:
    为标题化合物7开发了一种简单的,无催化剂,水介导的,一锅四组分的绿色方案,起始于芳族醛(1),丙二腈(2),1,3-二酮(3)和N-氯代琥珀酰亚胺(NCS)在室温下按顺序加成反应。本文首次提出的方法是通过不寻常的重排,其中NCS与2-氨基-7,7-二甲基-5-氧代-4-芳基-5,6,7,8-四氢-4 H反应-chromene-3-carbontritrile(4),它是由醛和丙二腈的Knoevenagel缩合,然后迈克尔加成3形成的。此外,这种新颖的方案与各种醛和具有活性的C–H功能衍生物兼容,可实现高收率并遵循GAP化学原理。有趣的是,化合物4与NCS在酒精介质中反应时,得到2-氰基-6,6-二甲基-4-氧代-3-芳基-2,3,4,5,6,7-六氢苯并呋喃-2-羧酸酯(5) 。

    The supramolecular polymeric aggregation behaviour of these ILs has been studied through high-resolution electron spray ionization mass spectrometry (HR-ESI-MS). Furthermore, these ILs were applied as catalyst/phase transfer catalyst in the synthesis of tetrahydrobenzo[b]pyran and its derivatives. These reactions were conducted in aqueous medium under ultrasound assistance. The results suggested that

    2-Hydroxyethyl-1-ammonium 3-hydroxypropane-1-sulfonate ‘HAHS’ was synthesized as a novel ionic liquid and characterized by various techniques. ‘HAHS’ ionic liquid was efficiently applied as a multifunctional promoter for the three-component synthesis of 2-amino-3-cyano-4H-pyrans. The 2-amino-3-cyano-4H-pyrans were produced not only in high to excellent yields but also no toxic solvent or catalyst was used. ‘HAHS’ ionic liquid was recovered and reused four times without the considerable decreasing in its activity. The effect of hydroxyl groups in the structure of ‘HAHS’ ionic liquid on its catalytic activity was studied. Moreover, the biodegradability potential of the ionic liquid was examined using the 5-day biological oxygen demand closed bottle test and the results showed that ‘HAHS’ has remarkable biodegradability potential.

    RTILs exhibit supramolecular self-assembled polymeric aggregation due to noncovalent interactions. The influence of the aggregation behaviour of RTILs on catalytic activity is evident but still poorly understood. The present work focuses on establishing a relationship between the role of supramolecular self-assembly of RTILs on catalysis in organic reactions. Herein, we report four unreported, air
    由于非共价相互作用,RTIL表现出超分子自组装聚合物聚集。RTILs的聚集行为对催化活性的影响是显而易见的,但仍然知之甚少。目前的工作集中在建立RTILs的超分子自组装对有机反应催化的作用之间的关系。在此,我们报告了四种未报告的,空气和水稳定,无卤化物,C 2对称的第三代疏水性咪唑基室温离子液体(RTIL 1-4),它们的合成和催化4H-的合成的作用-色烯衍生物(四氢苯并[ b] pyran)和Knoevenagel缩合。RTIL显示出前所未有的溶解度/混溶性。RTIL显示2-氨基苯甲酸1,3-二己咪唑鎓[hhim] [OAB](RTIL-3)在产率和反应时间方面表现更好。利用ESIMS探索了超分子聚合聚集体,同时通过记录RTIL在无水乙醇中的电导率来计算临界聚集体浓度(CAC)。我们还使用流变学实验来探索控制RTILs液相中聚集体发生的力。
