copper-bis(oxazoline) complex was utilized to construct a highly functionalized spirolactam, a key intermediate in our projected total synthesis of the marine toxin, gymnodimine. Additional transformations, including a mild N-tosyl group deprotection, afforded a keto spirocyclic imine moiety, the proposed pharmacophore of gymnodimine. Thus, the prepared ketone is a potentially useful intermediate for conjugation
