摘要:
Zinc salts are used to effect the regio-selective acylation and alkylation of the 1-amino group of 4-O-substituted-2-deoxystreptamine-containing aminoglycosides. The 1-N-substituted derivatives of apramycin, 3'-hydroxyapramycin, certain .alpha. or .beta.-(lower alkyl)aprosaminides and certain .alpha. or .beta.-(substituted lower alkyl)-aprosaminides are new. The 1-N-substituted-4-O-substituted-2-deoxystreptamine aminoglycosides produced by the process of this invention are antibacterial agents.
