Ruthenium (IV) dioxide dihydrate in fluoro acidic medium was found to be a very efficient agent for the non phenolic oxidative coupling of diarylbutanes. We observed along with the expected aryl-aryl coupling, an unusual aryl-benzyl coupling, leading to a known class of lignans, the aryltetralins. Conformational studies of resultant and deoxyschizandrins were performed using high resolution NMR and
发现氟酸介质中的二水合钌(IV)二水合物是用于二芳基丁烷的非酚类氧化偶联的非常有效的试剂。我们与预期的芳基-芳基偶联(一种不寻常的芳基-苄基偶联)一起观察到,导致形成一类已知的木脂素即芳基四氢萘。使用高分辨率NMR和分子模型进行了所得和脱氧五味子素的构象研究。
