The first example of palladium-catalyzed enantioselectivedesymmetrization of 2,3-bicyclic hydrazines with arylboronic acids through a ring-opening process is described by using a chiral C2-symmetric N-heterocyclic carbene (NHC) palladium complex as the catalyst. The reaction can be performed under convenient conditions to give trans-1,2-disubstituted 3-cyclopentenes 3 with high regioselectivity in
