The author of 《Benzofurans. LIV. New access to hydroxybenzofurans》 were Rene, Loic; Royer, Rene. And the article was published in Bulletin de la Societe Chimique de France in 1973. Category: benzofurans The author mentioned the following in the article:
Hydroxybenzofurans were prepared in overall yields I 70, II 60, III 30, IV 55%, by cyclizing methoxysalicylaldehydes with ClCH2CO2Et to a mixture of Et methoxycoumarilate, methoxycoumarilic acid, and methoxybenzofuran. The coumarilic acid derivatives were decarboxylated with Cu in quinoline and the methoxybenzofurans were demethylated by pyridine-HCl. The experimental process involved the reaction of Ethyl 6-methoxybenzofuran-2-carboxylate(cas: 50551-57-0Category: benzofurans)
Ethyl 6-methoxybenzofuran-2-carboxylate(cas: 50551-57-0) belongs to benzofurans.Category: benzofuransBenzofurans containing one furan ring that have been implicated as psychoactive recreational drugs include 6-(2-aminopropyl)benzofuran (6-APB), 5-(2-aminopropyl)benzofuran (5-APB), 5-(2-ethylaminopropyl)benzofuran (5-EAPB), and 5-methylaminopropylbenzofuran (5-MAPB).
