The synthesis of the title compound, isolated from the brown kelp (Ecklonia radiata) or the giant clam (Tridacna maxima), is reported.Glycosidation of 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribose, either directly with (S)-1,2-di-O-benzylglycerol or via the derived orthoester with (S)-1,2-O-isopropylideneglycerol, led to two fully protected glycerol β-D-ribofuranosides.Subsequent chemical manipulations led to a common intermediate having a free hydroxy group at C 5 of the D-ribose residue.Replacement of this hydroxy group by a chlorine atom allowed the introduction of the dimethylarsinyl group at C 5 in a two-step procedure, and removal of protecting groups provided the natural product.
