Synthesis And Biological Activity Of The Chiral Imidazolinone Derivatives And B, <sub> 2 </ Sub> The O <sub> 3 </ Sub> / Al <sub> 2 </ Sub> The O <sub> 3 </ Sub> Applied Research

The dissertation consists of two parts.The first part is the study of chiral imidazolinone derivatives' synthesis and its biological activity's research.The second part is the study of B₂O₃/Al₂O₃.The first part is to summarize the study of the chiral imidazolinone derivatives,and to explore a new type of chiral imidazolinone derivatives' synthesis and the study of their biological activity of the corresponding study.Easy to get from the preparation of optically active compounds of chiral pesticides can effectively avoid the cumbersome enantiomer separation,but also to avoid asymmetric synthesis of optically active expensive reagents.Bioactive Compounds from the structure of the study and may be for us to find a pilot of the application,with independent intellectual property rights and the creation of environment-friendly efficient,safe,pollution-free pesticides varieties.The second part is to summarize the study of B₂O₃/Al₂O₃,and to discuss the three reactions promoted by B₂O₃/Al₂O₃ and the catalyst's application:(1) B₂O₃/Al₂O₃ as an efficient and recyclable catalyst for the highly regioselective synthesis ofβ-amino alcohols under solvent-free conditions.(2) B₂O₃/Al₂O₃ as a reusable and efficient catalyst for the regio-and chemoselective synthesis of enaminones.(3) B₂O₃/Al₂O₃-catalyzed One-Pot synthesis of dihydropyrimidinones under solvent-free conditions...
