Stereoselective synthesis of cis and trans 2-substituted 1-phenyl-3-azabicyclo[3.1.0]hexanes

The Stereoselective synthesis of cis and trans 2-methyl-1-phenyl-3-azabicyclo3.1.0]hexanes and 1,2-diphen-yl-3-azabicyclo3.1.0]hexanes from 2-oxo-1-phenyl-3-azabicyclo3.1.0]hexane is described. The relative stereochemistry of the products was established by nuclear magnetic resonance and molecular modeling studies.
