A new chiral heterocyclic 1,1-enediamine as a precursor to piperidines

Abstract

A new chiral 4,5-dihydroimidazole enaminoester (a heterocyclic 1,1-enediamine) has been prepared as a potential precursor to piperidines, via 2,4,5-triphenyl-4,5-dihydroimidazole prepared from benzaldehyde and ammonia.
