Abstract

A method of production of new prostaglandin derivatives represented by the formula **(See formula)** where A represents (see formula), one of the groups R3 or R4 represents a hydrogen atom and the other represents a straight or branched chain alkyl group containing 1 to 4 carbon atoms, one of the groups R5 or R6 represents a hydrogen atom and the other represents a hydroxyl group and one of the groups R7 and R8 represents a hydrogen atom and the other represents a straight or branched chain alkyl group containing 1 to 4 carbon atoms; whose procedure is to hydrolyze the compound represented by the formula: **(See formula)** where A, R3, R4, R5, R6, R7 and R8 have the same meaning as in the previous formula, one of the groups R1 or R2 represents a hydrogen atom and the other represents a hydroxyl group provided with a protecting group and R9 represents a protecting group from the hydroxyl group, in an organic solvent under acidic, neutral or alkaline conditions, at room temperature or by heating.
