Synthesis of both the enantiomers of methyl epijasmonate
摘要:
Both the pure enantiomers of methyl epijasmonate 1 with potato-tuber inducing activity were synthesized steroselectively starting from 2-oxabicyclo[3.3.0]-oct-6-en-3-one 6 in 20% yield through 11 steps.
A unified strategy to prostaglandins: chemoenzymatic total synthesis of cloprostenol, bimatoprost, PGF<sub>2α</sub>, fluprostenol, and travoprost guided by biocatalytic retrosynthesis
Development of efficient and stereoselective synthesis of prostaglandins (PGs) is of utmost importance, owing to their valuable medicinal applications and unique chemical structures. We report here a unified synthesis of PGs cloprostenol, bimatoprost, PGF2α, fluprostenol, and travoprost from the readily available dichloro-containing bicyclic ketone 6a guided by biocatalytic retrosynthesis, in 11–12
An efficient and stereoselective synthesis of optically active clavulones has been accomplished by the use of the unnatural type dichloro Corey lactone 1 as a chiral pool.
通过使用非天然型二氯内酯 1 作为手性池,高效、立体选择性地合成了具有光学活性的克拉维酮。
Access to a Key Building Block for the Prostaglandin Family via Stereocontrolled Organocatalytic Baeyer–Villiger Oxidation
entire family of prostaglandins according to Corey′s route. Furthermore, the reactivity and enantioselectivity of B‐V oxidation of racemic bicyclic cyclobutanones were evaluated and 90–99 % ee was obtained, representing one of the most efficient routes to chiral lactones. This studyfurther facilitates the synthesis of prostaglandins and chiral lactone‐containing natural products to promote drug discovery
