Preparation method of cycloenone compound containing α -cyano substituted quaternary carbon center |
| abstract |
The invention discloses a preparation method of an α -cyano substituted quaternary carbon center cyclic ketene compound, which belongs to the technical field of organic synthesis, wherein an aryl or alkenyl boron reagent and an alkynyl substituted disubstituted malononitrile compound are subjected to alkyne insertion and cyclization tandem reaction under the catalysis of a nickel complex and a ligand to obtain the α -cyano substituted quaternary carbon center cyclic ketene compound. |
