Reaction of 5- or 7-methoxy-2-tetralone with an α-bromoester using lithium diisopropylamide as the base gave tricyclic naphtho[2,1-b]furan-2-ones in one step. Catalytic reduction, epimerization with triethylamine and microbial transformations yielded several related analogues. Some naphtho[2,1-b]furan-2-ones showed anti-inflammatory and breast cancer migration inhibitory activities.
以二异丙基酰胺锂为碱,将 5 或 7-甲氧基-2-四氢萘酮与 α-溴酯反应,一步即可得到三环萘并[2,1-b]呋喃-2-酮。通过催化还原、与三乙胺的环化反应以及微生物转化,得到了几种相关的类似物。一些萘并[2,1-b]呋喃-2-酮具有抗炎和抑制乳腺癌迁移的活性。
