I have recently came across this article "Copper(I)-Catalyzed [4 + 1] Cycloaddition of Silyl Dienol Ethers with Sodium Bromodifluoroacetate: Access to β,β‐Difluorocyclopentanone Derivatives". (Org. Lett. 2016, 18 (18), 4502–4505)

Can anyone explain what is the use of these β,β‐Difluorocyclopentanone Derivatives or where can I find more information about this cycloaddition procedure. Thanks in advance!
