Efficient Synthesis of a Range of 1-Hydroxy-2-(1-Alkyloxymethyl)-9,10-Anthraquinone Derivatives
Autor: Hashem Sharghi, Ali Forghaniha
Publikováno v: Iranian Journal of Chemistry & Chemical Engineering, Vol 14, Iss 1, Pp 16-22 (1995)
Five new 1-hydroxy-2-(1-alkyloxymethyl)-9,10-Anthraquinones (9a-e) have been prepared. Selective nitration of 2-methyl-9,10-anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydr
