A synthesis of 2-epi-fagomine via a highly stereoselective gold(I)-catalysed allene cyclisation is described. The stereochemical outcome of the cyclisation is opposite to that observed in previous studies. In contrast, gold(III)-catalysed cyclisation is inefficient and gives rise to double cyclisation by-products.
描述了通过高立体选择性金(I)催化的烯丙基环化合成2- epi- fagomine。环化的立体化学结果与先前研究中观察到的相反。相反,金(III)催化的环化效率低下,并导致双环化副产物的产生。
