    Abstract: Disclosed is a method for preparing a prostaglandin derivative of formula (A): which comprises reacting an aldehyde represented by formula (1): with a 2-oxoalkyl phosphonate in a reaction solvent under the presence of alkali hydroxide as sole base. By carrying out the reaction using an alkali hydroxide as sole base in the reaction system, the desired prostaglandin derivative can be obtained by simple procedures and with high yield.

    Abstract: A generator driving apparatus is provided with a thyristor driving device for driving a motor-generator, and the thyristor driving device always controls the driving of the motor-generator regardless of the number of rotations thereof. Also, when the motor-generator is coming to a stop, energy conserved in the motor-generator is regenerated to an electric power system through the thyristor driving device.
