Novel 5-alkylidene-2-halo-4-substituted-2- cyclopentenone and process for production thereof. The novel 5-alkylidene-2-halo-4-substituted-2-cyclopentenones are represented by the following formula (I):
wherein Ra represents a substituted or unsubstituted aliphatic hydrocarbon group having 1 to 12 carbon atoms or a substituted or unsubstituted phenyl group, Rb represents a substituted or unsubstituted aliphatic hydrocarbon group having 1 to 12 carbon atoms, and X represents a halogen atom. The novel cyclopentenones possess excellent pharmaceutical activities including anti-tumor activity, antiviral activity and antimicrobial activity.
