  A remarkable ene-like reaction: Development and synthetic applications

  摘要：

  A catalytic ene-like reaction of aldehydes with those vinyl ethers that display the oxygen functionality at the central carbon of an allylic system, e.g., 2-methoxypropene, is discussed in detail. The reaction is promoted by 0.05 eguiv. of the 1:1 complex of Yb(fod)(3) and acetic acid, and it is forms the centerpiece of our synthesis of chlorovulone II, mitomycinoids and phyllanthocin.

  Yb(fod)3-promoted ene reaction of aldehydes with vinyl ethers

  摘要：

  Catalytic amounts of Yb(fod)3 catalyze a bimolecular ene-like reaction between ordinary aldehydes and vinyl ethers, in which the oxygen functionality is located at the central carbon of an allylic system, These reactions proceed at room temperature in high yield.

• Practical Synthesis of (±)-Chlorovulone II
  作者：Marco A. Ciufolini、Shuren Zhu

  DOI：10.1021/jo972073f

  日期：1998.3.1

  We describe a total synthesis of (+/-)-chlorovulone II that is 10 steps shorter than the best alternative currently available (nine vs 19 steps). The key event of the synthesis is an aldol addition of the enolate of ethyl acetate into 4-cyclopentene-1,3-dione, a substance that has received little attention as an educt for prostanoid synthesis and for which little is known about carbonyl 1,2-addition with enolates. In addition, we provide chemical and stereochemical details of a route to a key intermediate toward the title compound that involves a carbonyl-ene reaction and a radical addition to an aldehyde carbonyl.
