标题:Efficient And Scalable Enantioselective Synthesis Of A Cgrp Antagonist
摘要:An Enantioselective Synthesis Of The Cgrp Antagonist Bms-846372,Amenable To Large Scale Preparation,Is Presented. This New Synthesis Showcases A Chemo-And Enantioselective Reduction Of A Cyclohepta[b]Pyridine-5,9-Dione As Well As A Pd-Catalyzed Alpha-Arylation Reaction To Form The Key Carbon-Carbon Bond And Set The Absolute And Relative Stereochemistry.
