The separate, and combined, influences of ether, silyl ether and cyclic ketal groups at positions 3 and 5 on the mode and efficiency of 6-heptenoyl radical cyclizations have been studied with a view to the eventual synthesis of 1α,25-dihydroxyvitamin D3.

Substituted carbocycles, tetrahydrofurans, and tetrahydropyrans can be efficiently obtained from omega-unsaturated carboxylic acids. Our methodology involves a Kolbe decarboxylation followed by in intramolecular radical cyclization and a radical-radical cross-coupling process.
