Syntheticbiology approaches achieving the reconstruction of specific plant natural product biosynthetic pathways in dedicated microbial “chassis” have provided access to important industrial compounds (e.g., artemisinin, resveratrol, vanillin). However, the potential of such production systems to facilitate elucidation of plant biosynthetic pathways has been underexplored. Here we report on the..
Au-Catalyzed Asymmetric Polyene Cyclization and Its Application in the Total Synthesis of (+)-2-Ketoferruginol, (+)-Fleuryinol B, (+)-Salviol, and (−)-Erythroxylisin A
shift/polyene cyclization cascade has been achieved with good enantioselectivities under the catalysis of the chiral Au(I) reagent. The synthetic utility of this method has been showcased by the catalytic asymmetric total syntheses of (+)-2-ketoferruginol, (+)-fleuryinol B, and (+)-salviol. Notably, the firstenantioselective total synthesis of (−)-erythroxylisin A has also been realized in 15 steps.
在手性 Au(I) 试剂的催化下,实现了催化不对称 1,3-酰氧基转移/多烯环化级联,具有良好的对映选择性。(+)-2-ketoferruginol、(+)-fleuryinol B 和 (+)-salviol 的催化不对称全合成展示了该方法的合成实用性。值得注意的是,(−)-erythroxylisin A 的首次对映选择性全合成也通过 15 个步骤实现。
