4-Formylindole - Reference Information
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| Overview | Indole -4-formaldehyde is an important pharmaceutical and organic chemical intermediate, which can synthesize many compounds with physiological and pharmacological activities, such as Ergoline compounds can be used to treat Parkinson's disease (or tremor paralysis) and prevent the release of lactogen. |
| Synthesis method | Using methyl 2-methyl-3-nitrobenzoate as raw material, indole -4-methyl formate is synthesized by L-B method Methyl ester, then isobutoxy aluminum hydride or lithium aluminum hydride is reduced to obtain 4-hydroxymethyl indole, and finally oxidized with active MnO2 or potassium permanganate to obtain indole -4-formaldehyde. |
| Uses | Biginelli reaction reagent; Aurora kinase A inhibitor synthesis reagent; Reagents for preparing anti-tumor additives; Reagents for intramolecular Friedel-Crafts acylation reactions; Reagents for preparing inhibitor reagents for cell division in Escherichia coli; Reagents for Hanchi synthesis reactions containing pyridine Schiff bases |
