Abstract An efficient synthetic pathway is described for 5,7-dimethoxy-4-methylphthalide, a key intermediate in the synthesis of mycophenolic acid and its analogues. The procedure starts from methyl 3,5-dimethoxybenzoate and involves five simple steps to give phthalide 3 in 55% overall yield.
摘要 5,7-二甲氧基-4-甲基苯酞是合成霉酚酸及其类似物的关键中间体,描述了一种有效的合成途径。该程序从 3,5-二甲氧基苯甲酸甲酯开始,包括五个简单的步骤,以 55% 的总收率得到邻苯二甲酸酯 3。
