Abstract
Described is a method for the preparation of 6'-modified fortimicin compounds including 6'-epi fortimicin by converting 1,2-di-N-protected fortimicin B into 4,6'-di-N-substituted alkoxycarbonyl-1,2'-di-N-protected fortimicin B which is further converted to 1,2'-di-substituted fortimicin B-4,5-carbamate, a compound whose substitution pattern is particularly suited to modification at the 6'-amino group and novel compounds thereof.
