In this Letter, we describe a novel approach for the general and enantioselectivesynthesis of a diverse array of small to large 1-azabicyclo[m.n.0]alkyl ringsystems with an embedded olefin handle for further functionalization. The stereochemistry is established via a highly diastereoselective indium-mediated allylation of an Ellman sulfinimine in greater than 9:1 dr, which is readily separable by
