Cycloreversion of alpha-lithiated phenyltetrahydrofuran was successfully tamed at -78 degrees C in a non-coordinating solvent in the presence of TMEDA. This anion showed excellent nucleophilicity and could be intercepted with a variety of structurally different electrophiles to give 2,2-disubstituted derivatives which can be further elaborated to gamma-butyrolactones.
在存在TMEDA的情况下,在非配位溶剂中于-78℃成功驯化了α-苯基苯基四氢呋喃的环还原。该阴离子显示出优异的亲核性,可以被多种结构不同的亲电体截获,从而生成2,2-二取代的衍生物,可以将其进一步加工成γ-丁内酯。
