Name: 4-Aminobutan-1-olIn 2019 ,《Sustainable methine sources for the synthesis of heterocycles under metal- and peroxide-free conditions》 appeared in Green Chemistry. The author of the article were Senadi, Gopal Chandru; Kudale, Vishal Suresh; Wang, Jeh-Jeng. The article conveys some information:
Alcs. and ethers were identified as sustainable methine sources for synthesizing quinazolinones I [R = H, 8-Me, 7-NO2, etc.; R1 = OMe, allyl, Ph, etc,] and benzimidazoles II [R2 = H, 5-Cl, 6,7-di-Me, etc.] using a combination of TsOH·H2O/O2 and appropriate bis-nucleophiles for the first time. Deuterium labeling studies clearly proved that the C2 hydrogen of the synthesized heterocycles came from the methine source. These unique reaction conditions were successfully applied to the synthesis of echinozolinone I [R = H; R1 = CH2CH2OH, 2-(1H-indol-3-yl)ethyl] (a common precursor of rutaecarpine and (±) evodiamine) and dimedazole II [R2 = 5,6-di-Me]. Notable features of this method included its low toxicity, use of com. feedstocks as substrates, low cost, broad functional group tolerance and suitability for a wide range of bis-nucleophilic starting materials. In the experiment, the researchers used many compounds, for example, 4-Aminobutan-1-ol(cas: 13325-10-5Name: 4-Aminobutan-1-ol)
4-Aminobutan-1-ol(cas: 13325-10-5) is used in the synthesis of NSAIDs with anti-inflammatory properties. Also used in the synthesis of polyamine transport ligands with specificity against human cancers allowing easy access to specific cancer cells.Name: 4-Aminobutan-1-ol
