The visible light-induced decarboxylative cascade reaction of fluoroalkyl carboxylic acids has been achieved for the efficient synthesis fluorinated compounds. However, most transformations rely on noble iridium metal complex. Herein, a metal-free realized. This protocol features simple operation, transition free, and good functional group tolerance.

A convenient and straightforward approach for the radical cascade cyclization/hydrolysis of CN-containing 1,6-enynes with simple ethers under metal- base-free conditions is described. This strategy provides a variety valuable ethers-substituted polyheterocycles via construction three C-C bonds, one C=O bond, two new six-membered rings within single procedure. The resulting products can smoothly undergo follow-up conversions to various useful scaffolds. methodology shows excellent functional group tolerance, high step- atom- economy, mild reaction conditions, which be further scaled up gram quantity in satisfactory yield.
