Abstract Treatment of tertiary β-nitro alcohols I, obtained by addition of lithium α-lithionitronates to ketones, with acetic anhydride followed by 1 equivalent of potassium methoxide or t-butoxide, according to the nature of R2, gives α-nitroalkenes III in good yields.
摘要 根据 R2 的性质,用乙酸酐和 1 当量的甲醇钾或叔丁醇处理由 α-亚硝基锂加成到酮中得到的叔 β-硝基醇 I,得到良好的 α-硝基烯烃 III产量。
