Expeditious Synthesis of Multisubstituted Quinolinone Derivatives Based on Ring Recombination Strategy

Yokoo, Kazuma,Mori, Keiji

supporting information, p. 244 - 248 (2019/12/30)

We achieved a concise construction of 3-substituted quinolinone derivatives based on a ring recombination strategy. In this process, seven transformations involving two types of cyclization proceeded in one pot to afford various quinolinone derivatives in good to excellent chemical yields (up to 98%).
