A double Hauser–Kraus annulation between biscyanophthalide 4 and the d-mannose derived enone 39 provides access to an advanced intermediate 54 that is an excellent scaffold to effect an enantioselective total synthesis of crisamicin A 1.
在双氰基酞化物4和d-甘露糖衍生的烯酮39之间进行的双重Hauser-Kraus环空法可提供进入高级中间体54的通道,该中间体是影响crisamicin A 1的对映选择性全合成的优良骨架。
