  The first example of γ-chloromagnesio γ-lactones: their generation from γ-tolylsulfinyl γ-lactones with isopropylmagnesium chloride, stability, and reaction with electrophiles

  摘要：

  The treatment of gamma-lactones having a sulfinyl group at the gamma-position, which were synthesized from I-chlorovinyl p-tolyl sulfoxides with lithium enolate of carboxylic esters, with isopropyl magnesium chloride in THF at -78 degrees C gave gamma-chloromagnesio gamma-lactones by the sulfoxide-magnesium exchange reaction in high yields. The generated gamma-chloromagnesio gamma-lactones were found to be stable at below -50 degrees C for at least 2 h. The reaction of these gamma-chloromagnesio gamma-lactones with electrophiles and the stereochemistry of the reactions were investigated. (c) 2006 Elsevier Ltd. All rights reserved.

  respectively, by the sulfoxide-magnesium exchange reaction in high yields. Comparing the stability of the γ-chloromagnesio γ-lactones with that of the δ-chloromagnesio δ-lactones, the former was found to be much more stable. The reaction of these γ-chloromagnesio γ-lactones and δ-chloromagnesio δ-lactones with electrophiles and the stereochemistry of the reactions are discussed. γ-chloromagnesio γ-lactone

  在异丙醇中于-78℃下用异丙基氯化镁处理在γ和δ位具有亚磺酰基的γ和δ内酯，分别通过亚砜处理得到γ-氯镁γ-内酯和δ-氯镁δ-内酯。 -镁交换反应的收率很高。通过比较γ-氯镁γ-内酯和δ-氯镁δ-内酯的稳定性，发现前者更加稳定。讨论了这些γ-氯镁γ-内酯和δ-氯镁δ-内酯与亲电试剂的反应以及反应的立体化学。 γ-氯镁γ-内酯-δ-氯镁δ-内酯-亚砜-镁交换反应-有机镁化合物-格氏试剂
