2-Formyl-3-protected hydroxy-5-oxocyclopent-1-eneheptanoic acid and its esters are stereoselectively reduced to the corresponding 2.beta.-formyl-3.alpha.-protected hydroxy-5-oxocyclopentane-1.alpha.-heptanoic acid and esters with chromous sulfate. The compounds so produced are useful as intermediates to PGE.sub.1 and its esters, which compounds exhibit hypotensive and smooth muscle-stimulating properties.
2-甲酰基-3-保护羟基-5-氧代环戊-1-烯庚酸及其酯类可通过铬酸钠的立体选择性还原,得到相应的2-β-甲酰基-3-α-保护羟基-5-氧代环戊烷-1-α-庚酸及其酯类。这些化合物可作为合成PGE.sub.1及其酯类的中间体,这些化合物具有降压和平滑肌兴奋作用。
