Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Hydroxyquinoline | HCID 6038 | — |
| Reactant | 4-Hydroxy-1-phenyl-1,2-dihydroquinolin-2-one | HCID 54676161 | — |
| Product | 3-(Hydroxymethylidene)-1-phenylquinoline-2,4(1H,3H)-dione | HCID 135454227 | — |
Reaction Steps
Following the procedure set forth in Preparation B, 1- phenyl-4-hydroxy-2(1H)-quinolinone was converted to 1 -phenyl-3-formyl-4-hydroxy-(2(1H)-quinolinone. That the expected product was obtained was confirmed by the spectral data: MS: m/e 265 (M·+); NMR (DMSO): δ10.08 (s, 1H, CHO) ppm.
