    摘要: Six-membered cyclic carbonates (2-oxo-1,3-dioxanes) in which keto or carbohydrocarbyloxy groups are bound to the 5 position of the ring are disclosed. They react surprising quickly with primary or secondary cyclic amines, and the novel product hydroxyurethanes are useful as reactive diluents.
