Abstract Three molecules of l -ristosamine (3-amino-2,3,6-trideoxy- l - ribo -hexopyranose) condense with one molecule of ammonia to give a stable compound [1.1′.1′′-(dodecahydro-1,4,7,9 b -tetrazaphenalene-2,5,8-trityl)tri-1,2-propanediol] reminiscent of the mode whereby formaldehyde and ammonia condense to form hexamethylenetetramine. The structure of the crystalline hexaacetate of this compound has been determined by X-ray crystallography. The mass-spectral fragmentation pattern and the 13 C-n.m.r. signals shown by the acetylated compound are assigned.
