Yang, Xiaoyu published the artcileRedox-triggered switchable synthesis of 3,4-dihydroquinolin-2(1H)-one derivatives via hydride transfer/N-dealkylation/N-acylation, Computed Properties of 197958-29-5, the publication is Organic Letters (2021), 23(2), 358-364, database is CAplus and MEDLINE.
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, resp. The unprecedented strategy for the synthesis of 3,3′-highly functionalized 3,4-dihydroquinolin-2(1H)-one has been realized with the in situ utilization of the released HCHO via the o-QM involved Michael addition In addition, the synthetic utility of this protocol has been well illustrated via concise synthesis of CYP11B2 inhibitor.
