During efforts to expand the scope of Lewis-acid-catalyzed [4+2] cycloaddition between donor–acceptorcyclobutanes and nitrosoarenes, an unexpected formation of pyrrolidine products was discovered when 50 mol-% of MgI2 was used as a Lewis acid. It was also observed that the electronics of the nitrosoarene and judicious selection of the Lewis acid catalyst have a profound effect on the regioselectivity

literature that provide trifluoromethylated versions of these compounds have prompted us to investigate a 1,3-dipolarcycloaddition route providing access to N-functionalized isoxazolidines containing a trifluoromethyl group. Thus, a 1,3-dipolarcycloaddition of nitrosoarenes, (trifluoromethyl)diazomethane, and alkenes was developed. The starting materials can be synthesized from easy to handle and accessible

multifunctionalized perfluoroalkyl aziridines via a ruthenium–perfluoroalkylcarbene intermediate is described. With Ru(p-Cl-TPP)CO as the catalyst, in situ generated CnF2n+1CHN2 from CnF2n+1CH2NH3Cl underwent a cascade of nitrone formation/1,3-diploar cycloaddition/rearrangement reactions with nitrosoarenes and alkynes to give a variety of multifunctionalized perfluoroalkyl aziridines in good to high yields and
描述了一种通过钌-全氟烷基卡宾中间体高效合成新的多官能化全氟烷基氮丙啶的方法。以Ru(p -Cl-TPP)CO为催化剂,由C n F 2 n +1 CH 2 NH 3原位生成C n F 2 n +1 CHN 2。C1与亚硝基芳烃和炔烃进行级联的硝酮形成/ 1,3-二齿环加成/重排反应,以高产率至高产率和中度至高非对映选择性地产生各种多功能全氟烷基氮丙啶。通过光谱分析了钌卟啉与C n F 2 n +1 CHN 2的化学计量反应得到的钌-全氟烷基卡宾中间体。
