  • Title: An entry to vinylcyclopropane through palladium-catalyzed intramolecular cyclopropanation of alkenes with unstabilized allylic tosylhydrazones.
    Author: Yang Y, Li J, Du B, Yuan C, Liu B, Qin S.
    Journal: Chem Commun (Camb); 2015 Apr 11; 51(28):6179-82. PubMed ID: 25753475.
    Abstract:
    A diastereoselective Pd-catalyzed intramolecular cyclopropanation of alkenes with unstabilized allylic tosylhydrazones was developed. This methodology provides an efficient entry toward synthesis of the bicyclo[3.1.0] hexane system with an exo-double bond, and sets the basis for future elaboration of more complex polycyclic motifs.
