A process for preparing a 1-deoxynojirimycin of the formula ##STR1## in which R is hydrogen, optionally substituted alkyl or aralkyl, which comprises converting D-glucose to an aminosorbitol ##STR2## protecting the amino group of the aminosorbitol with an alkalinically detachable group to form the protected compound of the formula ##STR3## in which X is an alkalinically detachable protective group, microbiologically oxidizing the protected compound to an oxidation product of the formula ##STR4## alkalinically splitting off the protective group X to form an aminosorbose of the formula ##STR5## and reducing the aminosorbose.
一种制备公式##STR1##中R为氢,可选取代烷基或芳基烷基的1-去氧诺吉霉素的方法,包括将D-葡萄糖转化为氨基山梨醇##STR2##,用碱性可分离基团保护氨基山梨醇的氨基基团形成保护化合物的公式##STR3##,其中X为碱性可分离保护基团,微生物氧化保护化合物以得到氧化产物的公式##STR4##,碱性分离保护基团X以形成公式##STR5##的氨基葡糖醛,然后还原氨基葡糖醛。
