Synthesis of Cylindricine derivative

This is a synthesis of a cylindricine 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. The synthesis of the SM has now also been added..
