主　　题：Mannich reaction β-Amino carbonyl compounds PEG-OSO_3H Environmentally benign 

摘      要：Sulfuric acid-modified polyethylene glycol 6000（PEG-OSO_3H） was applied as an efficient and recyclable catalyst for the synthesis ofβ-amino carbonyl compounds via the Mannich reaction between aldehydes,aromatic ketones and aromatic amines at room temperature using PEG400-H_2O（1：1） as environment-friendly *** reactions were completed in short times and mild reaction conditions with good to excellent yields.
