  Synthesis of .beta.-resorcylic macrolides via organopalladium chemistry. Application to the total synthesis of (S)-zearalenone

  摘要：

  The beta-resorcylic macrolides are a class of naturally occurring 12- and 14-membered macrolides. Zearalenone (1), a 14-membered macrolide of this type, displays useful biological activity, which has led to great synthetic interest. In this paper the intramolecular coupling reaction of an organostannane with an electrophile is used to construct beta-resorcylic macrolides. The intramolecular coupling of an aryl iodide with a vinylstannane provided the highest yield of lactones. This methodology was then used to prepare (S)-zearalenone (1).

• Total Synthesis of Aigialomycin D:  Surprising Chemoselectivity Dependence on Alkyne Structure in Nickel-Catalyzed Cyclizations
  作者：Christa C. Chrovian、Beth Knapp-Reed、John Montgomery

  DOI：10.1021/ol702961v

  日期：2008.3.1

  The total synthesis of aigialomycin D was carried out using a nickel-catalyzed ynal macrocyclization as a key step. This key step allowed macrocycle assembly and formation of a disubstituted alkene and a secondary hydroxyl stereocenter in a single step, although the stereocenter was formed unselectively. An interesting side reaction involving five-membered-ring synthesis by an aldehyde/styrene cyclization

  使用镍催化的ynal大环化作为关键步骤进行了aigialomycin D的全合成。该关键步骤允许大环组装并在一个步骤中形成二取代的烯烃和仲羟基立体中心，尽管立体中心是非选择性形成的。当尝试炔基硅烷的大环化时，观察到一个有趣的副反应，涉及通过醛/苯乙烯环化合成五元环。为这一令人惊讶的过程提供了机械基础。
• First Total Synthesis of Cassiarin A, a Naturally Occurring Potent Antiplasmodial Alkaloid
  作者：Marcellino Rudyanto、Yuichiro Tomizawa、Hiroshi Morita、Toshio Honda

  DOI：10.1021/ol8004112

  日期：2008.5.1

  The first total synthesis of cassiarin A, an antiplasmodial alkaloid isolated from Cassia siamea, was achieved via sequential alkynylation of arenes with Sonogashira coupling and 6- endo-dig-cyclization of phenolic oxygens to the resulting alkynes.

  决明子A（一种从决明子中分离得到的抗疟原虫生物碱）的第一个全合成是通过将芳烃与Sonogashira偶联依次进行炔基烷基化和酚内氧的6-内切-环化反应生成的炔烃而实现的。
