The synthesis of N-acetyl-1,2-didehydrodopamine (6; N-acetyl-3,4-dihydroxystyrylamine) was accomplished by demethylation of N-acetyl-3,4-dimethoxystyrylamine (5), formed by sequential treatment of 3,4-dimethoxycinnamic acid (1) with thionyl chloride, sodium azide, heat and methyl magnesium bromide.
N-乙酰基-1,2-二脱氢多巴胺(6;N-乙酰基-3,4-二羟基苯乙烯胺)的合成是通过 N-乙酰基-3,4-二甲氧基苯乙烯胺 (5) 的去甲基化完成的,N-乙酰基-3,4-二甲氧基苯乙烯胺 (5) 是通过连续处理 3、 4-二甲氧基肉桂酸(1)与亚硫酰氯、叠氮化钠加热,与甲基溴化镁反应。
