Condensation of 1,3-bis-<I>N</I>-(benzyloxycarbonyl)actmamine (<B>2</B>) with 2-<I>O</I>-chloroacetyl-4,6-dideoxy-3-<I>O</I>-<I>p</I>-nitrobenzoyl-α-D-xylohexopyranosyl chloride (<B>8</B>), followed by deacylation and catalytic hydrogenation afforded 5-<I>O</I>-(4,6-dideoxy-β-D-xylohexopyranosyl)actinamine (<B>11</B>). Compound <B>11</B> was found to be identical with one of the four tetrahydrospectinomycins. <SUP>1</SUP>H and <SUP>13</SUP>C NMR spectra were determined and analyzed.
