Burke laboratory. Thus, according to the devised strategy, the mixed 1,2-bisborylated vinyl linchpin was consecutively functionalized with 5-bromodienal derivatives in a doubly orthogonal fashion. However, when the synthetic material was matched against the bacterial isolate, inconsistencies were observed. A re-examination of the cryptic natural product was conducted by juxtaposing analytical data from
表型引导的转座子诱变已成为获取细菌基因组中编码的神秘代谢物的宝贵工具。最近,该方法通过在Burkholderia thailandensis中诱导沉默的生物合成基因簇得到证实。在分离的代谢产物中,thailandene A 表现出良好的抗生素活性。通过分配,线性多烯醛包含一个不稳定的基序,其中表面上的手性仲醇交织在烯丙基和同烯丙基星座中。我们的注意力被吸引到异质功能之间的伪对称关系,表明十二戊烯支架的转变。以迭代交叉耦合协议为中心,分配的 all- E- (12 R)-羟基十二五烯醛部分是通过将 Zincke 化学与 Burke 实验室开发的 MIDA-attenuated Suzuki 反应相结合来组装的。因此,根据所设计的策略,混合的 1,2-双硼化乙烯基关键销被 5-溴二烯醛衍生物以双正交方式连续官能化。然而,当合成材料与细菌分离物匹配时,观察到不一致。通过并列来自实验和密度泛函理论
