The highly diastereo‐ and enantioselective relay cascade Michael/Michael/Henryreaction catalyzed by combination of readily available diphenylprolinolsilylether and the quinine thiourea in a one‐pot fashion has been developed. Up to 70% yield and up to >99% enantioselectivity of the single major isomer were obtained from the cascade reactions.
已经开发出了一种高非对映选择性和对映选择性中继级联Michael / Michael / Henry反应,该反应通过容易获得的二苯基脯氨醇甲硅烷基醚和奎宁硫脲的单锅法进行催化。从级联反应中获得了单一主要异构体的最高70%的收率和最高> 99%的对映选择性。

A facilesynthesis of [5,5]-annulated N-fused heterocycles – pyrrolo[2,1-b]thiazoles and pyrrolo[1,2-b]indazoles via oxidative [3+2]-annulation between nitroalkenes and azolium ylides in the presence of copper(II) was developed. The reaction proceeds in mild conditions with the copper(II) trifluoroacetate/2,6-lutidine system. The method is applicable to a broad range of nitroalkenes and azolium salts
通过硝基烯烃和唑鎓叶立德之间的氧化 [3+2] -环化,轻松合成 [5,5]-环化 N-稠杂环 - 吡咯并 [2,1- b ] 噻唑和吡咯并 [1,2- b ] 吲唑铜(II)的存在被开发出来。该反应在温和条件下使用三氟乙酸铜 ( II )/2,6-二甲基吡啶体系进行。该方法适用于广泛的硝基烯烃和唑盐,以中等至良好的产率提供目标 N-稠杂环。在 α-氟硝基烯烃的情况下,通过这种方法获得了独特的氟化衍生物。
Ionic liquid-promoted stereoselective [3 + 2] cycloaddition of 1-hetaryl-2-nitroethenes to azomethine imines generated in situ

Ionic liquids facilitate regio- and stereoselective [3+2] cycloaddition of 1-hetaryl-2-nitroethenes to azomethine imines generated catalytically from 6-Ar-1,5-diazabicyclo[3.1.0]hexanes in the presence of BF3 center dot Et2O. The similar reaction is possible in MeCN only for azomethine imine with Ar = 2,4-(MeO)(2)C6H3 to give a mixture of two diastereomers.
