The addition of tin or silicon nucleophiles to bicyclic enones generated by dearomatising cyclisation gives starmanes and silanes stereo selectively. These compounds may be fragmented under oxidative conditions to generate substituted pyrrolidines bearing C2 and C3 substituents closely related to those found in the kainoid series of cyclic amino acids.
