An expedient concise total synthesis of (+)‐7‐epigoniodiol, (−)‐8‐epigoniodiol, and (+)‐9‐deoxygoniopypyrone is accomplished. The key transformations include a catalytic hydroxylation and base‐mediated N‐(acetyl)oxazolidinone addition reactions, which could set the consecutive OH motif that is either syn,syn or syn,anti with high diastereoselectivity. Moreover, this approach envisioned to facilitate
实现了(+)-7-庚二醇,(-)-8-表庚二醇和(+)-9-脱氧goniopypyrone的简便,简便的全合成。密钥变换包括催化羟基化和碱介导ñ - (乙酰基)恶唑烷酮加成反应,其可以设置连续OH基序或者是顺式,顺式或顺式,反具有高非对映选择性。而且,该方法被设想为促进具有结构和立体化学变化的家族的其他代表的合成。
