موضوع به انگلیسی:Bifunctional C2-symmetric ionic liquid-supported (S)-proline as a recyclable
organocatalyst for Mannich reactions in neat condition
بخشی از متن:
bi-functional C2-symmetric ionic liquid-supported (S)-Proline organocatalyst [BHEDIMP][CF3CO2] has been
designed and synthesized for the first time. The novel C2-symmetric organocatalyst [BHEDIMP][CF3CO2] (4 mol
%) was employed for the one-pot multi-component Mannich reactions comprising of substituted acetophenones,
arylamines, and aryl aldehydes to yield racemic β-amino ketones derivatives in neat conditions. This present
synthetic method is highlighted by numerous advantages such as low catalyst loading percentage, solvent-free
synthesis, short reaction times, easily accessible substrates, and devoid of chromatography purification. The
supported C2-symmetric organocatalyst was recycled and reused six times without substantial damage to its
catalytic efficiency
