摘要:
A compound represented by the following formula ÄIÜ or an optically active substance or a salt thereof. (In the formula, a bond shown by a dotted line in the five-membered ring means that said five-membered ring may be any of a cyclopentene ring having a double bond and a cyclopentane ring where said bond is saturated and, in the case of a cyclopentene ring, X is OH, Y is =O and Z is H while, in the case of a cyclopentane ring, X is =O, Y is OH and Z is OH. R is a residue after removal of an SH group from the SH-containing compound.)
