Azabicyclic ring skeletons are common structural subunits present in numerous alkaloid natural products and serve as important scaffolds in biologically active and pharmaceutically significant compounds.[1] Of particular interest in our laboratory (Figure1), are the indolizidine 1, pyrroloACHTUNGTRENNUNG [1, 2-a] azepine 2, and pyrroloACHTUNGTRENNUNG [1, 2-a] azocine 3 azabicyclic systems,[1] which are found ...
