Neutrality is the best policy: Key features of the first total synthesis of paecilospirone include an anti‐selective, lactate‐derived aldol reaction, and a double deallylation/spirocyclization conducted at neutral pH to construct the sensitive hydroxy‐substituted benzannulated spiroacetal (see scheme; Bn=benzyl, TBS=tert‐butyldimethylsilyl, TES=triethylsilyl).
中性是最好的政策:培西洛酮的第一个全合成的关键特征包括抗选择性,乳酸衍生的醛醇缩合反应,以及在中性pH值下进行的双脱甲酰/螺环化反应,以构建敏感的羟基取代的苯并环化螺缩醛(参见方案; Bn =苄基,TBS =叔丁基二甲基甲硅烷基,TES =三乙基甲硅烷基)。
