The regioselective decarboxylation of nitroalkanoates synthesized from Baylis–Hillman acetates of acrylates proceeds stereoselectively to afford homoallyl nitroalkanes. In contrast, nitroalkanoates derived from Baylis–Hillman acetates of acrylonitrile gave bisallyl nitroalkanes. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
由丙烯酸酯的 Baylis-Hillman 醋酸酯合成的硝基链烷酸酯的区域选择性脱羧反应立体选择性地进行,得到高烯丙基硝基烷烃。相比之下,从丙烯腈的 Baylis-Hillman 醋酸酯衍生的硝基链烷酸酯得到双烯丙基硝基烷烃。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
