  • Supported and Unsupported Chiral Squaramides as Organocatalysts for Stereoselective Michael Additions: Synthesis of Enantiopure Chromenes and Spirochromanes
    作者:José M. Andrés、Jorge Losada、Alicia Maestro、Patricia Rodríguez-Ferrer、Rafael Pedrosa
    DOI:10.1021/acs.joc.7b01177
    日期:2017.8.18
    Novel supported chiral bifunctional squaramides have been easily prepared starting from diamines derived from natural amino acids and commercially available aminoalkyl polystyrene resins. These squaramides behave as excellent stereoselective recoverable organocatalysts in different Michael additions, in neat conditions at room temperature. The reaction on 2-(2-nitrovinyl) phenol as electrophile lead
    从衍生自天然氨基酸的二胺和可商购的氨基烷基聚苯乙烯树脂开始,已经容易地制备了新型的负载性手性双官能方酸酰胺。在室温下的纯净条件下,这些麦角酰胺在不同的迈克尔添加量下均表现为出色的立体选择性可回收有机催化剂。以2-(2-硝基乙烯基)苯酚为亲电试剂,以优异的收率和对映选择性,反应生成易于转化为4 H-色烯和螺并二氢吡喃酮的中间体。

    作者:Pinar Kasaplar、Paola Riente、Caroline Hartmann、Miquel A. Pericàs
    DOI:10.1002/adsc.201200526
    日期:2012.11.12
    A chiral squaramide has been supported onto a polystyrene (PS) resin through a copper-catalyzed azide–alkyne cycloaddition (CuAAC) reaction and used as a very active, easily recoverable and highly reusable organocatalyst for the asymmetric Michael addition of 1,3-dicarbonyl compounds to β-nitrostyrenes. The PS-supported squaramide could be recycled up to 10 times.
    通过铜催化的叠氮化物-炔烃环加成(CuAAC)反应,将手性方酰胺被负载在聚苯乙烯(PS)树脂上,并用作非常活泼,易于回收和高度可重复使用的有机催化剂,用于1,3-二羰基不对称迈克尔加成反应β-硝基苯乙烯的化合物。PS支撑的方胺最多可回收10次。

    motifs in organocatalysis, whereas efficient 1,3‐diamine‐derived organocatalysts are very rare. Herein we report a highly efficient camphor‐1,3‐diamine‐derived squaramide organocatalyst. Its catalytic activity in Michael additions of 1,3‐dicarbonyl nucleophiles to trans‐β‐nitrostyrene derivatives provides excellent enantioselectivities (up to >99% ee).

    作者:György Kardos、Tibor Soós
    DOI:10.1002/ejoc.201300626
    日期:2013.7
    accessible, and robust immobilized bifunctional organocatalysts. There was no need to employ any tether to secure high enantio- and diastereoselectivities in various Michael addition reactions. The synthetically useful Michael adducts were obtained within reasonable reaction times with the advantage of easy product isolation and the possibility of automation by using a flow chemistry apparatus.
