Mild Base-Promoted Tandem Nucleophilic Substitution/Decarboxylation/Hydroamination: Access to 3-Sulfonylindoles and 2-Methyleneindophenols was written by Chen, Guifang;Xu, Bo. And the article was included in Organic Letters in 2021.Quality Control of 4-Benzyloxyphenol The following contents are mentioned in the article:
An efficient construction of 3-sulfonylindoles and 2-methyleneindophenols via decarboxylative propargylation/hydroamination of ethynyl benzoxazinanones using sodium sulfonates and phenols as the nucleophiles was developed. The reaction featured mild conditions (K2CO3), simple operation, and high chemoselectivity and was transition-metal-free. The present protocol could also be extended to other nucleophiles, including malonates, alcs., and indoles. The broad substrate scope and scalability made this protocol practical for the synthesis of indole derivatives This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Quality Control of 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Quality Control of 4-Benzyloxyphenol
