investigated. Both polyfluoroalkyliodide and ethyl iododifluoroacetate, gave rise to fluorine-containing γ-butyrolactones as the main products while bromides such as ethyl bromodifluoroacetate gave the addition–reduction product. After steric and stereo effects on reaction yields were studied using various substrates, it was concluded that the reactions of 4-pentenamides and polyfluoroalkyliodides provide one
研究了由Na 2 S 2 O 4引发的含氟卤化物向4-戊烯酰胺的自由基加成反应。聚氟代烷基碘和碘代二氟乙酸乙酯均产生含氟的γ-丁内酯作为主要产物,而溴代二氟乙酸乙酯等溴化物则产生加成-还原产物。在使用各种底物研究了空间和立体反应对反应收率的影响之后,得出的结论是,4-戊烯酰胺与多氟烷基碘的反应提供了一种制备具有氟化侧链的γ-丁内酯的替代方法。

straightforward strategy for the synthesis of 4-(fluoroalkyl)oxazolidin-2-ones via one-pot addition-intramolecular N-cyclization of allyl carbamates with fluoroalkyliodides is presented. The reaction proceeded in moderate to good yield through regiocontrol and an increase in the reactivity of the ambident nucleophiles by the use of alkali metallic reagents. allyl carbamates - 4-(fluoroalkyl)oxazolidin-2-ones -

A triple-tandem protocol for the synthesis of the pyrrolizidinone skeleton has been devised. It involves a cross metathesis–intramolecular aza-Michael reaction–intramolecular Michael addition tandem sequence, starting from N-pentenyl-4-oxo-2-alkenamides and conjugatedketones. In the presence of two cooperative catalysts, namely the second-generation Hoveyda–Grubbs catalyst and (R)-TRIP-derived BINOL
