SUMMARY
In the Kiliani-Fischer synthesis of aldopentose, the formation of a γ lactone is favored over a δ lactone despite the latter being a six-membered ring, which typically suggests greater stability. The discussion highlights that the stability of lactones is influenced by factors beyond mere thermodynamics, including kinetic aspects. Reference to specific figures, such as Figure 7, Series 4 from the provided link, illustrates the underlying mechanisms affecting lactone formation.
