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

Abstract The synthesis and antioxidant activity of novel cyclitol, lactone and epoxidederivatives starting from appropriate 1.4-cyclohexadiene are reported in this study. All structures of these products were characterized by 1H NMR, 13C NMR, MS and IR spectroscopy. The antioxidant capacities of some synthesized compounds were studied by using the methods of the scavenging effect on DPPH (2,2-dip
摘要 本研究报道了以适当的 1.4-环己二烯为原料合成新型环醇、内酯和环氧化物衍生物及其抗氧化活性。这些产物的所有结构均通过 1H NMR、13C NMR、MS 和 IR 光谱表征。采用清除DPPH(2,2-diphenyl-1-picrylhydrazyl)自由基的方法研究了部分合成化合物的抗氧化能力。可以看出,五个合成分子中有两个的抗氧化特性接近于 α-生育酚。
