Stepwise degradation of the sidechain in portulal has been investigated in connection with synthetic studies. Selective cleavage of the double bond in the sidechain was achieved by ozonolysis after protection of the endo-double bond by iodoetherification of the corresponding alcohol. Further degradation led to the formation of the γ-lactone via the δ-lactone.
