2,3-Epoxycyclopentanones are described having substituents in the 4-position or in both 4- and 5-positions. When both 4- and 5-positions are substituted, the 4-substituent is a substituted or unsubstituted aliphatic hydrocarbon group, and the 5-substituent is a hydroxyl- or carboxyl-containing group. When the 4-position only is substituted, one 4-substituent is hydroxyl or protected hydroxyl, and the second 4-substituent is a substituted or unsubstituted aliphatic hydrocarbon group. These compounds have anti-tumor or bone formation acceleration activity, or are intermediates for preparing such compounds.
