摘 要:首先以异喹啉为原料,经氧化生成氮氧化物后与苯甲酰氯和水作用,得到1-羟基异喹啉,收率为73.3%.以Fasudil为原料,经氨基保护、氧化,在相转移催化剂的存在下,于二氯甲烷和水的两相体系中与苯甲酰氯和水作用,合成羟基Fasudil,HPLC纯度大于99%,总收率为46.8%,从而建立了一条条件温和、操作简便的羟基Fasudil的合成工艺路线.1-Isoquinolinol was synthesized from isoquinoline via oxidation,reaction with benzoyl chloride and water in yield of 73.3%.According to this process,a method for the synthesis of hydroxyfasudil [1-(1-hydroxy-5-isoquinolinesulfonyl)-ho-mopiperazine] from fasudil [hexahydro-1-(5-isoquinoline-sulfonyl)-1H-1,4-diazepine] was estabilshed in this paper.The proc-ess undergoes effectively through protection for amino,oxidation,reaction with water in a water/dichloromethane biphase system in the presence of phase transfer catalyst and benzoyl chloride and then deprotection.The objective product was finally obtained in yield of 46.8% with a purity more than 99%(HPLC).It is virtually a practical process with mild reaction condi-tions and simple operation.
