- PROSTANOIDS. XXIX. SELECTIVE OXIDATION OF 7α-HYDROXY-6β-HYDROXYMETHYLENE-2-OXABICYCLOOCTAN-3-ONE BISTRIMETHYLSILYL ETHER BY REAGENTS BASED ON CHROMIUM(VI) AS KEY STAGE IN SYNTHESIS OF SULPROSTONE
-
7α-Hydroxy-6β-(3-oxo-4-phenoxy-1E-butenyl)-2-oxabicyclooctan-3-one was synthesized by the selective oxidation of 7α-hydroxy-6β-hydroxymethylene-2-oxabicyclooctan-3-one bistrimethylsilyl ether with CrO3*2Py/SiO2 and subsequent condensation of the intermediate 7α-trimethylsiloxy-6β-formyl-2-oxabicyclooctan-3-one with dimethyl 2-oxo-3-phenoxypropylphosphonate.The product was then converted into the methanesulfonamide of 16-phenoxy-17,18,19,20-tetranorprostaglandin E2 (sulprostone).

- N-(Methanesulfonyl)-16-phenoxyprostaglandincarboxamides: Tissue-Selective, Uterine Stimulants
-
In an effort to develop tissue-selective prostaglandin analogues resistant to the metabolic inactivating pathways of the natural materials, hybrid compounds modified both at C-1 with a sulfonimide moiety and in the n-amylcarbinol side chain with substituted phenoxy groups were synthesized and evaluated in a variety of in vitro and in vivo models.Several of these analogues exhibited potent, tissue-selective, uterine stimulant activity, a finding subsequently confirmed in clinical studies with one member of this series, N-(methanesulfonyl)-16-phenoxy-ω-tetranor-PGE2-carboxamide (CP-34089/ZK-57671, sulprostone).
