A new synthesis of the ajoene pharmacophore core is presented involving the regioselective radical addition of a thiyl radical to a terminal alkyne as the key step. The synthesis allows structural variation of the two end groups on sulfur, and a range of novel derivatives varying the R(1) group (sulfoxide end) has been prepared and tested against CT-1 transformed. broblast cells for anti-cancer activity. The results indicate comparable or even improved activity compared to the parent natural product ajoene isomers. This opens up the way to systematically studying the biology of the ajoene core.

We describe a short total synthesis of ajoene, a major biologically active constituent of garlic. The instability of allicin as the only other known alternative starting material has led to the development of a reliable procedure for the synthesis of ajoene from simple building blocks that is also suitable for upscale operations.
