    摘要: 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.
