标 题:Synthesis of prostaglandins of the 'one'-series
发明人：SCHAAF THOMAS K; COREY ELIAS J
权利人:PFIZER
摘要:In the synthesis of prostaglandins of the 'one' -series an alteration in the conventional reaction sequence avoids side reactions and provides an improved synthesis via a series of novel intermediates. In this improved synthesis the side chain at the 8 position is attached to the five membered ring before the side chain at the 12 position is attached.
