摘要: Publisher Summary This chapter elaborates chemical advances in prostaglandins (PG). Nasal decongestion, lowering blood pressure, treating gastric ulcers, infertile semen, inducing labor, and thrombosis are some of the promising therapeutic areas that being investigated for prostaglandins. The syntheses PGE1 PGE2 their racemic its optically active presented. Their synthetic sequences particularly characterized by mild specific reaction conditions. first two from this group involved an intramolecular aldol condensation to generate desired cyclopentanol, followed transformation amino at C-9 a ketone function. penta substituted cyclopentane was synthesized six step stereoselective sequence starting with cyclopentadienyl sodium. Lactone transformed five steps α,β-unsaturated ketone. converted more PGF2. A also developed whereby C-11 C-15 alcohols can be protected as tetrahydropyranyl (THP) ethers generated oxidation leading PGE2.
