opening of bicyclic hydrazines and bicyclic oxazines with organomagnesium reagents under the influence of copper catalysts allows functionalized cyclopentene and cyclohexene derivatives to be obtained. Whereas complete anti-stereoselective ring opening occurred in all cases, the regioselective outcome turned out to be highly dependent on the reaction conditions used. The ring opening of bicyclic hydrazines
