A synthesis of 2-epi-fagomine via a highly stereoselective gold(Ⅰ)-catalyzed allene cyclization is described.The stereochemical outcome of the cyclisation is opposite to that observed in previous studies.In contrast, gold(Ⅲ)-catalysed cyclization is inefficient and gives rise to double cyclization by-products.
