✦ Synopsis

Previous letters' have established the molecular formula of butirosins A (Ia) and B (Ib) as C21H41Ns01.s and have shown that three of the structural units, (S)-(-)-4-amino-Z-hydroxybutyric acid (II), neosamine C (2,6-diamino-2,6-dideoxy-D-glucose) (III), and a pentose (Dxylose (IVa) in Ia, D-ribose (IVb) in Ib), are individually attached, as amide and O-glyco-

This accounts for 22 carbons and 23 protons. The three missing protons belong to 3 hydroxyl groups, which was confirmed by acetylation of 1 to form a triacetate [3, m/z 528 (M+)].
