paper, a new and efficient synthesis of 6-O-methylscutellarein (3), the major metabolite of the natural medicine scutellarin, is reported. Two hydroxyl groups at C-4′ and C-7 in 2 were selectively protected by chloromethyl methyl ether after the reaction conditions were optimized, then 6-O-methyl-scutellarein (3) was produced in high yield after methylation of the hydroxyl group at C-6 and subsequent deprotection
在本文中,报道了一种新型高效合成 6-O-甲基黄芩苷 (3),天然药物黄芩苷的主要代谢物。优化反应条件后,2中C-4′和C-7的两个羟基被甲基氯甲醚选择性保护,羟基甲基化后高收率得到6-O-甲基-黄芩素(3)在 C-6 和随后的两个甲基醚基团的脱保护。
