Method for preparing prostaglandin derivative |
| 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. |
