| use | intermediate for static experience. |
| Production method | Use resorcinol to catalyze and isomerize with nickel with the participation of potassium hydroxide to generate 3-ketocyclohex-1-enol potassium, and then cyclize with ethyl bromopyruvate to obtain 4-oxo-4, 5,6, 7-tetrahydrogulonic acid -3, then use ammonia to replace the oxygen on the furan ring and eliminate (decarboxylation) to obtain the product. |
