New, General, and Practical Enamine Cyclopropanation Using Dichloromethane
摘要:
Dichloromethane serves as a novel electrophilic carbene equivalent which adds to an enamine double bond. The presence of other alkene moieties in the enamine partner is well tolerated. Even enamines derived from sterically hindered ketones react readily with dichloromethane promoted by TiCl4-Mg.
