【 摘 要 】

2-pyrrolidinon-3-olates were synthesized via one-pot four-component reaction of 2-aminobenzothiazole, aromatic aldehydes, dimethyl acetylenedicarboxylate and morpholine/piperidine in the presence of Co3O4@SiO2 core–shell nanocomposite as catalyst under ultrasound irradiation. The protocol offers several such advantages as high yields, short reaction time and mild reaction conditions with reusability of the catalyst. The core–shell nanocomposite was also prepared using ultrasound irradiation and the structure and magnetic properties were fully characterized by TEM, FE-SEM, XRD, EDX, FT-IR and VSM analysis.
