The Mukaiyama-Michael reaction of 2-(trimethylsilyloxy)furan with α′-phenylsulfonyl enones using bis(oxazoline)-copper(II) complexes as chiral catalyst provides the γ-butenolides in high enantio- and diastereoselectivity. This approach is very useful for the enantioselective synthesis of γ-butenolide derivatives under chiral Lewis acid catalysis.
使用双(噁唑啉)-铜(II)络合物作为手性催化剂,使 2-(三甲基硅氧基)呋喃与δ′-苯磺酰基烯酮发生 Mukaiyama-Michael 反应,以高对映选择性和非对映选择性生成δ³-丁烯内酯。这种方法对于在手性路易斯酸催化下对δ-丁烯内酯衍生物的对映选择性合成非常有用。
