title: Copper-catalysed ring opening of polycyclic meso-hydrazines with trialkylaluminium reagents and SimplePhos ligands.
abstract: meso-Hydrazines could be desymmetrised by ring-opening reactions by using various metal catalysts to form substituted cyclopentenes, which have a high synthetic potential. Herein, we report the asymmetric copper-catalysed ring opening of a range of polycyclic hydrazines with trialkylaluminium reagents and SimplePhos ligands with both high isolated yields and enantioselectivities of up to 95 %.
