The conversion of the naturally abundant cyclitol, myo-inositol (4), into (+)-nojirimycin (1a), its enantiomer (1b), and their 1-deoxy analogues (2a and 2b) is described. Biological assay of 2a, 2b, and the bisulfite adducts of 1a and 1b (3a and 3b) showed that the compounds having the unnatural L-gluco configuration (2b and 3b) possess moderate-to-high inhibitory activity against almond beta-D-glucosidase
描述了将天然丰富的环糖醇肌醇(4)转化为(+)-纳吉霉素(1a),其对映异构体(1b)和它们的1-脱氧类似物(2a和2b)。对2a,2b和1a和1b的亚硫酸氢盐加合物(3a和3b)的生物学分析表明,具有非天然L-葡萄糖构型的化合物(2b和3b)具有对杏仁β-D-的中等至高抑制活性。葡萄糖苷酶和牛肝β-D-半乳糖苷酶。
