A novel synthetic route to (−)-anisatin has been developed. Our synthesis features a rhodium-catalyzed 1,4-addition of an arylboronic acid, an intramolecular Diels–Alder reaction of an ortho-quinone monoketal, a stereoselective [2,3]-Wittig rearrangement, and construction of the oxabicyclo [3.3.1] skeleton via cleavage of an epoxide by a primary amide.
已开发出一种新颖的合成途径来合成(-)-茴香胺。我们的合成具有芳基硼酸的铑催化的1,4-加成,邻醌单缩酮的分子内Diels-Alder反应,立体选择性[2,3] -Wittig重排和氧杂双环[3.3.1]的构建。通过伯酰胺裂解环氧化物来形成骨架。
