Abstract Nitroaldol reaction of acetone with nitromethane in the presence of base to give a nitroalcohol 3, followed by acetylation, and subsequent reduction of the resultant acetate 4 with NaBH4 gave 2-methyl-1-nitropropane 5. Michael reaction of 5 in base with acrylonitrile to give nitronitrile 6, and Nef conversion of the nitro group resulted in the corresponding ketonic nitrile 7. Wittig olefination
摘要 丙酮与硝基甲烷在碱存在下的硝基羟醛反应得到硝基醇 3,然后乙酰化,随后用 NaBH4 还原所得乙酸酯 4 得到 2-甲基-1-硝基丙烷 5。 5 在碱中与丙烯腈的迈克尔反应得到腈 6,硝基的 Nef 转化得到相应的酮腈 7。酮腈与 3-甲基-2-丁烯基三苯基溴化鏻 8 的 Wittig 烯化得到二烯腈 9,用 MeLi 处理,然后用酸性后处理,提供异茄酮 2。
