Allenic acids are found to add to dicyclohexylcarbodiimide affording, in the presence of secondary amines, the 1,3-oxazine-4-ones. 5. Under neutral conditions, they add to diaryl- or aryl(cyclohexyl)carbodiimides and triphenylketen-imine to give the corresponding tricyclo[5.2.2.01,5]undecatriene-3-ones 7-9 and 12.
