Amino-alcohol cyclization: selective synthesis of lactams and cyclic amines from amino-alcohols [PDF]
Catal. Sci. Technol., 2014 By employing an amination catalyst, previously used in the direct synthesis of amines from alcohol with ammonia, n-amino-alcohols could be selectively cyclized to either the amide or the amine. By the addition of water, the amine could be produced as the major product whereas adding a sacrificial ketone as a hydrogen acceptor resulted in the amide as ...
