Process for preparing pyrrole derivatives and intermediates

摘要

The present invention relates to a process for preparing pyrrole derivatives of a class that is effective at inhibiting the biosynthesis of cholesterol in humans, and more particularly to improved synthetic methods for preparing 3,5-dihydroxy-7-pyrrol-1-yl heptanoic acids from 1,4-diketo starting materials. The invention further relates to intermediates in this process:
