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

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.
