New stable nitroxides, analogous to TEMPO (tetramethylpiperidine-N-oxyl) where two α,αⲠmethyl groups are formally replaced by ester functions, are prepared via dienolate chemistry followed by a deprotectionâoxidation sequence.
新稳定
氮氧自由基,类似于
TEMPO(四甲基
哌啶氮氧化物),其中两个α,α'甲基被酯官能团形式取代,通过二烯醇化物
化学法结合脱保护-氧化序列制备而成。
