Spherical oxygenated heteropolycycles 3 , containing stable acetal groups of a hitherto unknown type, can be obtained with surprising ease by the action of simple enamines 1 ( n = 1–4) on the diketone 2 . An ene addition is followed by a thermal [2 + 2 + 2] cycloaddition of the two carbonyl groups to the enamine double bond. Mor = morpholino.
