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.
一种制备式为##STR1##的1-去氧诺基霉素的方法,其中R是氢,可选择性地取代的烷基或芳基,包括将D-葡萄糖转化为氨基山梨醇##STR2##,保护氨基山梨醇的氨基团以形成式为##STR3##的保护化合物,其中X是碱性可分离的保护基团,微生物氧化保护化合物以得到氧化产物的方法,其化学式为##STR4##,碱性地去除保护基团X以形成山梨醛胺##STR5##,并还原山梨醛胺。
