为了合成新的[ n ]对环环烷,研究了Winterfeldt等人最初公开的策略范围的扩展。这种方法涉及顺序的Diels-Alder / retro-Diels-Alder反应,到目前为止,其应用仅限于类固醇衍生物。使用热电环化和环加成/环还原序列作为关键步骤,从容易获得的构建基块中开发出了有效访问新型功能化的[9]-,[10]-和[16]对环烷,包括原始的笼式体系结构的方法。
A new method for converting 2-alkynyl arylazide derivatives into functionalized polysubstituted quinolines following a gold-catalyzed 1,3-acetoxy shift/cyclization/1,2-group shift sequence has been developed. This transformation proceeds under mild reaction conditions, is efficient, and tolerates a large variety of functional groups.
