Schiff base

(shif),
condensation products of aldehydes and ketones with primary amines; the compounds are stable if there is at least one aryl group on the nitrogen or carbon. Compare: ketimine.
Synonym(s): aldimine

Color changes were also observed as the reaction evolved, which could be attributed to the aldimine binding reactions (CH = N) that occur when an aldehyde group (-CHO) reacts with an amino group during the crosslinking process.
In the catalysis of PLP-dependent enzymes, the transaldimination reaction is strictly conserved and happens at least two times in forward and reverse directions: the forward reaction is from the internal aldimine to the external aldimine and the reverse reaction is vice versa (Scheme 1).
Hydroamination of alkyne 2 with amine 6 yields the aldimine intermediate 7.

Regioisomeric nitro-tetrahydroquinolines 3 and 4 were easily prepared via the protocol of a "one pot" three-component imino Diels-Alder reaction between in situ forming N-aryl aldimines and trans-anethole in the presence of B[F.sub.3].
Reverse-docking study of the organocatalyzed asymmetric Strecker hydrocyanation of aldimines and ketimines.
Imines [11], both aldimines and ketimines due to presence of carbon-nitrogen bond in their molecules, provides a potential site for chemical [12-13] as well as biological [14-15] activity, but very less work has been carried out on synthesis of [alpha],[beta]-unsaturated ketimines.
In addition, cure rates can be lowered by utilizing blocked NHs (i.e., aldimines and ketimines) that become active upon reacting with atmospheric moisture and/or formulating with ASP-based secondary diamines.
The aim of the present work was to fill this gap and investigate the pinacol coupling of aldimines in the presence of mischmetall (Ce and La), Zn-Cu couple, and Dewarda alloy (50% Cu, 5% Zn, 45% Al).
