Reaction of 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose with 2-methoxyadenine to form 9-(2′,3′,5′-tri-O-benzoyl-β-D-ribofuranosyl)-2-methoxyadenine, then deprotection of the 9-(2′,3′,5′-tri-O-benzoyl-β-D-ribofuranosyl)-2-methoxyadenine to form spongosine is described. Synthesis of intermediates for use in the synthesis of spongosine is also described.
