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.
1-O-乙酰基-2,3,5-三-O-苯甲酰基-β-D-核糖呋喃糖与2-甲氧基腺嘌呤反应生成9-(2’,3’,5’-三-O-苯甲酰基-β-D-核糖呋喃糖基)-2-甲氧基腺嘌呤,然后去保护9-(2’,3’,5’-三-O-苯甲酰基-β-D-核糖呋喃糖基)-2-甲氧基腺嘌呤生成海绵素的过程已被描述。同时也描述了用于合成海绵素的中间体的合成。
