摘要：

The reduction of the oxo functions in ethyl 5-(6-ethoxycarbonylhexyl)-3,3-dimethyl-2,4-dioxocyclopentanecarboxylate (1) with NaBH4, with LiAlH(O-t-Bu)3 and by catalytic hydrogenation is described. Four isomeric hydroxycyclopentanones and four isomeric cyclopentanediols were isolated and their stereochemistry was determined, providing 1H-NMR and 13C-NMR data which should be useful in structural assignment of isomeric prostaglandin analogues.
