摘要:以L-阿拉伯糖为起始物,通过羟基保护、还原、脱保护等5步反应得到一种重要的L-脱氧核苷类药物中间体2-脱氧-L-核糖。在最后一步脱保护过程中,改用在醋酸水溶液中脱去苯甲基保护基团,单步产率由70%提高到92%,总收率提高到40%。化合物的结构用1HNMR、MS及元素分析法进行了表征。
2-Deoxy-L-ribose, an important intermediate of L-deoxynucleosides, was obtained by five steps reaction with L-arabinose as the starting material. In the last deprotection step we used acetic acid/water solution to take off the benzyl radical, the yield of the single step was increased from 70% to 92% ,and the overall yield was increased to 40%. Structures of the compounds were identified by ^1HNMR,MS and elementary analysis.
