A highly enantioselective Diels-Alder reaction of 1,2-dihydropyridine using a simple β-amino alcohol organocatalyst for a practical synthetic methodology of oseltamivir intermediate

摘要

An easily prepared chiral amino alcohol catalyst was found to provide an efficient synthetic intermediate of oseltamivir with excellent chemical yield and enantioselectivity (up to 98% yield and up to 98% ee) in enantioselective Diels-Alder reactions of 1,2-dihydropylidines with acroleins.
