Manufacturing method of prostaglandin intermediate |
| abstract |
(57) [Summary] [Purpose] In the prostaglandin production process, 5- The production ratio of the cis-form of the double bond at the 6-position is improved. [Constitution] When introducing an α-chain by reacting ylide with lactol in the prostaglandin production process, using an ylide obtained from a phosphonium salt and a potassium base, Use a solvent that is liquid at the reaction temperature and has a dipole moment of 0.3 to 30 as the reaction solvent. |
