An efficient enantio- and diastereocontrolled construction of hydrophenanthrenes having either a quaternary or a tertiary benzylic stereogenic center has been developed by employing a tandem retro-aldol and intramolecular Friedel-Crafts alkylation sequence. Its application to a diastereocontrolled synthesis of an abietane diterpenoid (+)-ferruginol has also been demonstrated.
通过使用串联的逆向羟醛和分子内Friedel-Crafts烷基化序列,已经开发了具有季铵或叔苄基立体异构中心的对菲的对映异构和非对映异构控制的有效构造。还已经证明了其在松果油双萜类(+)-ferruginol的非对映控制合成中的应用。
