efficient, regioselective and steresoselecitive one-pot protocol for the synthesis of (Z)-S-2-alkoxycarbonyl-3-acylallyl ethanethioates and (E)-S-2-cyano-3-acylallyl ethanethioates from benzaldehydes and activated alkenes (methyl acrylate and acrylonitrile) was developed. Our method consisted of Morita–Baylis–Hillman reaction of benzaldehydes and activated alkenes using DABCO followed by acetylation using
从苯甲醛和活化烯烃(甲基)合成 (Z)-S-2-alkoxycarbonyl-3-acylallyl 乙硫酸酯和 (E)-S-2-cyano-3-acylallyl 乙硫酸酯的有效、区域选择性和立体选择性一锅法丙烯酸酯和丙烯腈)。我们的方法包括苯甲醛和活化烯烃使用 DABCO 的 Morita-Baylis-Hillman 反应,然后使用乙酸酐和催化量的 DMAP 乙酰化,以及 SN2' 与 DMF 中硫代乙酸钾的反应。前两个反应在无溶剂条件下进行。图形概要
