A highly efficient and practical method for the synthesis of enantiomerically pure 4-alkoxy-2-alkyl-2-cyclopenten-1-ones 1, the key component for the preparation of prostaglandins via the two-component coupling process, has been developed. The method involves the preparation of 4-alkoxy-2-methylene-3-(tributylstannyl)cyclopentan-1-one 6 from readily available 4-alkoxy-2[(diethylamino)methyl]-2-cyclopenten-1-one 5 and its reaction with alkyl radicals.

Paragraph 0162-0167, (2021/05/01)
The invention provides an optically active cyclopentanone compound shown as a formula (I) and a preparation method thereof. The optically active cyclopentanone compound can be used for preparing key intermediates and derivatives thereof in prostaglandin synthesis. The invention also provides a method for synthesizing prostaglandin by using the optically active cyclopentanone compound. When the optically active cyclopentanone compound is used for synthesizing prostaglandin, the synthesis steps of prostaglandin can be remarkably shortened, the synthesis efficiency is improved, and the production cost is reduced.
