摘要：

Sulfuric acid-modified polyethylene glycol 6000 (PEG-OSO3H) was applied as an efficient and recyclable catalyst for the synthesis of a-amino carbonyl compounds via the Mannich reaction between aldehydes, aromatic ketones and aromatic amines at room temperature using PEG400-H2O (1:1) as environment-friendly solvents. The reactions were completed in short times and mild reaction conditions with good to excellent yields. (C) 2012 Xi Cun Wang. Published by Elsevier B.V, on behalf of Chinese Chemical Society.
