A series of ynenyl allyl ethers were rearranged into polysubstituted furans in the presence of a gold(I) catalyst. It is proposed that the transformation involves a Claisen-type rearrangement that allows the efficient creation of quaternary centers under mild experimental conditions.
在金(I)催化剂的存在下,一系列炔基烯丙基醚被重排成多取代呋喃。建议转换涉及克莱森型重排,允许在温和的实验条件下有效创建四元中心。
