We provide a full account of our synthetic studies targeting the hexacyclic calyciphylline B-type alkaloids, a subfamily of the Daphniphyllum natural products. Following an initial set of syntheticstrategies focused on constructing the piperidine core of the calyciphylline B-type framework via a 6π-azaelectrocyclization, as well as exploiting the reactivity of underexplored oxazaborinine heterocycles
