Abstract
Provided is a compound represented by the general formula (I) or a salt thereof:wherein, —XY— represents —CH═CH— and the like, between R2 and the carbon atom at 5-position represents a single bond or a double bond, R1 represents a lower alkyl group, a formyl group, a carboxyl group, a lower alkoxycarbonyl group (wherein a lower alkyl moiety of said lower alkoxycarbonyl group may be substituted with a heterocyclic group) and the like, and R1a represents a hydrogen atom, provided when R1 represents a lower alkoxycarbonyl group and the like, R1a may further represents a lower alkoxycarbonyl group and the like, when between R2 and the carbon atom at 5-position is a single bond, R2 represents a hydroxyl group and the like, and when between R2 and the carbon atom at the 5-position is a double bound, R2 combines with the carbon atom at 5-position to form a hydroxime group (—C(═NOH)) and the like, and R3 represents a hydroxyl group or a tri(lower alkyl)silyloxy group.
