Synthesis of Cylindracine derivative

This is a synthesis of a cylindracine derivative. The 14th step is a cyclization and has been omitted due to the fact that the particular reaction has not yet been published. However, any suitable cyclization could be used at this step. This synthesis was made slightly longer to allow for the incorporation of the specialized reaction. However, some might find the other synthetic transformations interesting/useful for similar structures. In figure 2 the 10th step is omitted, it was a cyclization, but there were problems with this synthetic method. My apologies: (previously the wrong figure was attacthed) but I've decided to keep both up to avoid confusion. :)
