[Aminooxy analogues of spermine and their monoacetyl derivatives].

ABSTRACT

Convenient methods of synthesis of 1-aminooxy-3,8-diaza-11-aminoundecane, its earlier unknown N1-and N1 -acetyl derivatives, and also 1,10-bis(aminooxy)-3,8-diazadecane are suggested. It is shown a possibility to selectively delete the acid-labile ethoxyethylidene protection of aminooxy group by hydrosulfates in the presence of N-tert-butyloxycarbonyl group.
