Several functionalized diazabicyclo[4.3.0]nonenes and other heterocycles have been prepared as potential peptidomimetic scaffolds. A novel and efficient method has been developed for the preparation of N-substituted gamma-lactams 13. Preparation of amidine-containing 1,5-diazabicyclo[4.3.0]nonenes 43 and 44 has been achieved through Hg-mediated
