Abstract
The intramolecular cyclisation of tethered allyl bromides onto terminal alkynes mediated by metallic indium proceeds smoothly and cleanly in an mixture of THF and water to give unsaturated carbocycles and heterocycles in good yield. The reaction does not proceed efficiently under rigorously anhydrous conditions.Keywords
