Efficient synthesis of 2,4,5-trisubstituted 2,5-chiral tetrahydropyridines using a one-pot asymmetric azaelectrocyclization protocol

摘要

The stereocontrolled synthetic procedure for the preparation of 2,4,5-trisubstituted 2,5-chiral 1,2,5,6-tetrahydropyridines was established using a one-pot asymmetric azaelectrocyclization protocol; the generality of this protocol was demonstrated by synthesizing the title compounds with various aryl and alkenyl substituents at the C-2 position.
