  Ring-Opening of 4-Isoxazolines: Competitive Formation of Enamino Derivatives and a,b-Enones

  摘要：

  Ring-opening of 3-substituted 4-isoxazolines, proceeding through the intermediate isoxazolinium salts, follows two competing reaction pathways leading to alpha,beta-enones and enamines respectively. The rearrangement courses can be controlled as a function of substitution pattern and experimental conditions.

  amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic aldehydes, conjugate aldehydes, and aliphatic aldehydes. Central to successfully driving the condensation series is the formation

  A new method for the synthesis of 2,3-dihydrofurans from readily available starting enones and pyridinium salts has been developed. This protocol can provide a novel and effective methodology for the preparation of 2,3-dihydrofurans in a stereoselective fashion. To increase the efficiency of this reaction the one-pot process was also developed, in which the pyridinium salts were generated in situ from

  The synthesis of a large number of β- and β,β-substituted keto esters was successful by the use of the Knoevenagel condensation reaction. The stereoselectivity of these reactions was improved by alteration of various substituent groups. Although there were few examples of complete Z selectivity, the use of tert-butyl acetoacetate with either aromatic or aliphatic aldehydes afforded Z selectivity. The selective reductions of these substituted keto esters was successfully achieved by using a combination of NaBH₄ and CeCl₃·7H₂O or Yb(OTf)₃, which allowed a facile synthesis of a large number of stereochemically pure substituted Morita–Baylis–Hillman adducts, including β,β-substituted adducts.

  大量β-和β,β-取代酮酯的合成成功地通过Knoevenagel缩合反应实现。通过改变各种取代基团来改善这些反应的立体选择性。尽管完全Z选择性的例子很少，但是使用叔丁基乙酰乙酸酯与芳香族或脂肪族醛可以获得Z选择性。这些取代酮酯的选择性还原成功地通过使用NaBH₄和CeCl₃·7H₂O或Yb(OTf)₃的组合实现，从而实现了大量立体化纯净的取代Morita–Baylis–Hillman加合物的简便合成，包括β,β-取代加合物。
