Abstract
The ring opening of bicyclic hydrazines and bicyclic oxazines with organomagnesium reagents under the influence of copper catalysts allows functionalized cyclopentene and cyclohexene derivs. 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 usedFile in questo prodotto:
