The tropane ring system (8-methyl-8-azabicyclo [3.2. 1]-octane) is an important substructure in a number of natural products and synthetic compounds of biological and medicinal importance. As a result of the significance of the tropane ring system, the development of new synthetic methodology for the preparation of useful tropane precursors for the construction of more complex molecules continues to be an important field of study. 1-11 ( ...
