A polycyclic collapse: Use of a carefully designed acyclic intermediate participated in a cascade reaction that formed the entire core of the polyketide‐derived dalesconols in a single flask (see scheme). A number of additional and carefully controlled synthetic operations completed an expeditious synthesis of both of these highly bioactive natural products as well as structural congenors.
