2-THIO-ETHER-2-CYCLOPENTENONES

摘要

2-thio-ether-2-cyclopentenones are described having two substitutents in the 4-position. The 2-thio substituent is of the type R1-S- where R1 is a substituted or unsubstituted hydrocarbon group. One substituent in the 4-position is a hydroxyl or protected hydroxyl, and the second 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.
