$N$-Substituted methyl 2-((azolyl)methyl)-3-arylacrylates were synthesized stereo- and regioselectively with one-pot reaction between Baylis--Hillman acetates and a suitable acylazole in the presence of K$_2}$CO$_3}$ as a base catalyst. The targeted $N$-substituted azole acrylates were efficiently obtained in good yields (39%-89%).
$N$-取代甲基2-((吡唑基)甲基)-3-芳基丙烯酸酯通过Baylis-Hillman醋酸酯与适当酰基吡唑在K$_2$CO$_3$基催化剂存在下的一锅法反应,立体和区域选择性地合成。目标的$N$-取代吡唑基丙烯酸酯以良好收率(39%-89%)高效获得。
