Derivatives of Ketipic Acid, II. - Ketipic Acid Dilactone and Related Compounds

The highly reactive title compound 7 was prepared by thermal decomposition of the disguised oxalylbisketene 6.Ring opening of 7 with nucleophiles leads to γ-alkylidenetetronic acids 4. α-Substituted derivatives of 4a give rise to unsymmetrical dilactones
