Base-Mediated One-pot Synthesis of Oxygen-Based Heterocycles from 2-Hydroxyphenyl-Substituted para-Quinone Methides was written by Singh, Gurdeep;Kumar, Suresh;Chowdhury, Arjun;Vijaya Anand, Ramasamy. And the article was included in Journal of Organic Chemistry in 2019.Reference of 6834-42-0 This article mentions the following:
One-pot synthesis of oxygen-containing heterocycles has been achieved through alkylation/acylation of 2-hydroxyphenyl-substituted para-quinone methides followed by an intramol. 1,6-conjugate addition/cyclization and oxidation sequence. This protocol provides access to a wide range of oxygen-based heterocycles, such as 2,3-disubstituted benzo[b]furans, 2,3-dihydrobenzofurans and diaryl-substituted coumarin derivatives in moderate to good yields. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0Reference of 6834-42-0).
2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Reference of 6834-42-0
