kingdom: A highly efficient and diastereoselective transannular oxy‐Michael reaction for the construction of the syn‐ and anti‐tetrahydropyran units from a common 14‐membered macrolactone is the key step for the total synthesis of aspergillide A and B (see scheme; CM=cross‐metathesis, HWE=Horner–Wadsworth–Emmons, TBS=tert‐butyldimethylsilyl).
键王国:用于建造一个高效和非对映选择性跨环氧迈克尔反应顺式-和反从一个共同的14元大环内酯-四氢吡喃单位为aspergillide A和B的总合成中的关键步骤(参见流程; CM =交叉复分解,HWE = Horner–Wadsworth–Emmons,TBS =叔丁基二甲基甲硅烷基)。
