Abstract
2-Substituted-2-cyclopentenones represented by the formula (I): ##STR1## wherein A is a hydroxyl group or ##STR2## and B is a hydrogen atom or A and B are bonded together to form one bonding arm; PA1 R.sup.1 represents a substituted or unsubstituted hydrocarbon group having 1 to 10 carbon atoms; PA1 R.sup.2 represents a substituted or unsubstituted aliphatic hydrocarbon group having 1 to 10 carbon atoms; PA1 R.sup.3 represents a substituted or unsubstituted aliphatic hydrocarbon group having 1 to 10 carbon atoms; wherein, PA1 when R.sup.3 is a single bond bonded to the cyclopentene skeleton, X represents a hydrogen atom, a hydroxyl group or a protected hydroxyl group; and PA1 when R.sup.3 is a double bond bonded to the pentene skeleton, X represents a bonding arm constituting a part of said double bond; and PA1 m and n independently represent 0, 1 or 2.
