Abstract
The first synthesis of the heterocyclic marine natural product, acremolin, is reported along with the revision of the structure from a 1H-azirine to a substituted N(2),3-ethenoguanine (5-methyl-7-isopropyl-4,5-dihydroimidazo[2,1-b]purine). Additional properties of acremolin are also described including its (1)H-(15)N-HMBC and fluorescence spectra.
摘要
本文首次报道了杂环海洋天然产物 acremolin 的全合成，并将其结构从 1H-氮丙啶修订为取代的 N(2)，3-亚乙基鸟嘌呤（5-甲基-7-异丙基-4,5-二氢咪唑并[2,1-b]嘌呤）。还描述了 acremolin 的其他性质，包括其 (1)H-(15)N-HMBC 和荧光光谱。
