The switchable synthesis of 3-non, 3-mono, 3,3′-disubstituted 3,4-dihydroquinolin-2(1H)-ones was developed through a redox-neutral hydride-transfer/N-dealkylation/N-acylation strategy from o-aminobenzaldehyde with 4-hydroxycoumarin, and Meldrum’s acid, respectively. The unprecedented strategy for the synthesis of 3,3′-highly functionalized 3,4-dihydroquinolin-2(1H)-one has been realized with the in
通过氧化还原-中性氢化物转移/ N-脱烷基/ N-酰化策略发展了3-非,3-单,3,3'-二取代的3,4-二氢喹啉-2(1 H)-ones的可转换合成分别由邻氨基苯甲醛与4-羟基香豆素和Meldrum酸组成。合成3,3'-高度官能化的3,4-二氢喹啉-2(1 H)-1的空前策略已实现,其中通过迈克尔加成通过o -QM原位利用释放的HCHO 。此外,通过简明合成CYP11B2抑制剂已很好地说明了该方案的合成效用。
