A nonconventional approach to the preparation of morphinans has been applied to the total synthesis of thebainone-A and β-thebainone-A. Noteworthy features of this synthesis are the regiospecificity of the Diels-Alder reaction to form 9 and of the enolization-hydroxylation of 11, the unusual aromatization of 14 as well as the selectivity of the intramolecular Michael addition of the of the anine to
一种制备吗啡喃的非常规方法已应用于蒂巴酮-A 和β-蒂巴因-A 的全合成。该合成的值得注意的特征是形成 9 的 Diels-Alder 反应和 11 的烯醇化-羟基化的区域特异性、14 的不寻常芳构化以及分子内迈克尔加成形成 41 的选择性。该路线提供了获得与吗啡相关的几种生物碱骨架的途径,并展示了合成芳香分子的新方法
