β¦ Synopsis
The first allylindation of norbornenoi derivatives has been realised highly regio-and stereoselectively. The reactions of allylindium sesquiiodide with syn-bicyclo[2.2.1 ]hept-2-en-7-oi and endo-bicyclo[2.2.1 ]hept-5-en-2ol gave ailylated products together with iodinated and oxygenated compounds. The product distribution could be controlled by changing the reaction solvent. In these reactions, the regio-and stereochemistry of the addition of the allylindium reagent is highly regulated via the chelation with the neighbouring hydroxyl group.
