Abstract A convenient and efficient synthetic route to 1-chloro-6-methoxy-isoquinolin-3-ol and its derivatives is reported. This new method involves carboxylation of 4-methoxy-2-methylbenzonitrile, subsequent conversion of the resulting 2-cyano-5-methoxy-phenylacetic acid to its acid chloride, and acid-promoted cyclization of the 2-cyano-5-methoxy-phenyl-acetyl chloride. This procedure offers a better
摘要 报道了一种简便高效的1-氯-6-甲氧基-异喹啉-3-醇及其衍生物的合成路线。这种新方法涉及 4-甲氧基-2-甲基苯甲腈的羧化,随后将所得 2-氰基-5-甲氧基-苯乙酸转化为其酰氯,以及酸促进的 2-氰基-5-甲氧基-苯基环化-乙酰氯。与之前报道的路线相比,该程序提供了更好的总产率,而且危险性更小,重现性更好。
