Herein, we employ unsaturated pyrazolones in the Rauhut–Currier reaction for the first time. A domino Rauhut–Currier cyclization reaction has been developed between unsaturated pyrazolones and nitro-olefins. The trisubstituted tetrahydropyrano[2,3-c]pyrazoles were obtained in moderate to high yields with excellent diastereoselectivities. A few applications including a synthesis of disubstituted tetrahydropyrano[2

吡唑啉酮。在不饱和
吡唑啉酮和硝基烯烃之间发展了多米诺Rauhut-Currier环化反应。三取代
四氢吡喃并[2,3- c ]
吡唑以中等至高收率获得,具有非对映选择性。已经证明了包括合成二取代的
四氢吡喃并[2,3- c ]
吡唑在内的一些应用。还使用手性
DMAP催化剂研究了该方法的初步催化不对称形式。
