cross‐coupling study of steroidal vinyl (pseudo)halides with different boronic acids and tributyltin organyls. Furthermore, we have investigated the “inverse” case of those cross‐coupling reactions, i.e., the reaction of a steroidal vinylpinacolatoborane or a tributyltin steroid with various bromides. The development of both methods allows the introduction of different residues at C‐17 of steroid skeletons
本文中,我们报告了甾体乙烯基(假)卤化物与不同的硼酸和三丁基锡有机基的Stille和Suzuki交叉偶联的比较研究。此外,我们研究了那些交叉偶联反应的“逆向”情况,即类固醇乙烯基松香烷硼烷或三丁基锡类固醇与各种溴化物的反应。两种方法的发展都允许在类固醇骨架的C-17处引入不同的残基,从而提供了广泛的类固醇类似物的途径,这对于生物学筛选或天然产物合成非常重要。
