Alkylation of 8-oxoadenosine (13) with 4-benzyloxy-3, 5-dibromobenzyl bromide (20), followed by Dimroth rearrangement and acid hydrolysis, provided N-(3, 5-dibromo-4-hydroxybenzyl)-8-oxoadenosine (15). The 2'-deoxy version of this reaction sequence accomplished the first synthesis of N-(3, 5-dibromo-4-hydroxybenzyl)-8-oxodenine (16), which is the correct expression for marine ascidian purine aplidiamine.
8-氧代腺苷 (13) 用 4-苄氧基-3, 5-二溴苄基溴 (20) 烷基化,然后进行 Dimroth 重排和酸水解,得到 N-(3, 5-二溴-4-羟基苄基)-8-氧代腺苷 ( 15)。该反应序列的 2'-脱氧版本首次合成了 N-(3, 5-二溴-4-羟基苄基)-8-氧化腺嘌呤 (16),这是海洋海鞘嘌呤 aplidiamine 的正确表达。
