Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 8-Aminonaphthol | HCID 94906 | — |
| Reactant | 5-Undecanone | HCID 98677 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 3H-Naphtho[1,2-e][1,2]oxazine | HCID 66604612 | 35.9% |
Reaction Steps
With 6.3 g of 8-amino-1-naphthol and 20 ml of ethanol, 8.1 g of 5-undecanone was mixed. The mixture was refluxed for 3 hours. The reaction mixture was condensed, and purified in a column chromatography (silica gel, n-hexane/ethyl acetate=1/6) to obtain 2.6 g of naphthooxazinine.
