  Synthesis of N-Alkyl-Substituted 4-Quinolones via Tandem Alkenyl and Aryl C-N Bond Formation

  摘要：

  N-Alkyl-substituted 4-quinolones are present as the key structural motif in many marketed drugs. An efficient one-step tandem amination approach was developed to afford N-alkyl-substituted 4-quinolones in high yields from easily accessible o-chloroaryl acetylenic ketones and functionalized alkyl amines. The approach complements and extends our previous work. Compared with other reported methods, the current method provides a very simple and convenient route.

  日期：2012.1

  Titanium dioxide‐supported silver nanoparticles were utilized as a highly efficient catalyst for the addition of terminal alkynes to aldehydes to prepare propargylic alcohols with the promotion by triphenylphosphine. Both a significant support effect and a ligand effect were observed in the catalytic reaction. With this protocol, various propargylic alcohol derivatives were synthesized from aldehydes

  二氧化钛负载的银纳米粒子被用作高效催化剂，用于将末端炔烃添加到醛中，以制备由三苯基膦促进的炔丙醇。在催化反应中观察到显着的支持作用和配体作用。通过该协议，可以从醛和末端炔烃以良好至极好的收率合成各种炔丙醇衍生物。此外，该催化剂可以有效地回收和再利用而不会明显降低催化活性。
