experimental part, p. 2527 - 2536 (2009/04/04)
A highly efficient two-step method for the synthesis of pyranoquinoline derivatives from imino-Diels-Alder reactions between aldimines and 3,4-dihydro-2H-pyran using niobium(V) chloride as catalyst under mild conditions is described. Georg Thieme Verlag Stuttgart.

A series of imines was synthesized by an ultrasound-assisted reaction of aldehydes and primary amines using silica as the promoter. Products were obtained in high yields even in large scale synthesis.
Isoprene-catalyzed lithiation of imidazole: Synthesis of 2-(hydroxyalkyl)- and 2-(aminoalkyl)imidazoles

2-Lithioimidazole was prepared by means of a new protocol, which consists of a slight excess of lithium metal in the presence of a substoichiometric amount of isoprene (20 mol%) in THF at room temperature. By reacting this organolithium with carbonyl elec
Rapid synthesis of quinoline-4-carboxylic acid derivatives from arylimines and 2-substituted acrylates or acrylamides under indium(III) chloride and microwave activations. Scope and limitations of the reaction

Rapid synthesis of quinoline-4-carboxylic acid derivatives has been achieved by reaction of 2-methoxy acrylates or acrylamides with N-arylbenzaldimines in acetonitrile under InCl3 catalysis and microwave irradiation. Isolated yields up to 57% within 3 min have been obtained. The Lewis acid and the microwave activation appeared as crucial parameters for the reaction. The role of indium chloride and ytterbium triflate was specified using 13C NMR data and model theoretical studies. The Royal Society of Chemistry 2005.
Spectroscopic and semi-empirical MO study of substituent effects on the intramolecular proton transfer in anils of 2-hydroxybenzaldehydes
Alarcon, Sergio H.,Pagani, Daniela,Bacigalupo, Jose,Olivieri, Alejandro C.
, p. 233 - 240 (2007/10/03)
Substituent effects in singly and doubly substituted anils of 2- hydroxybenzaldehyde showing strong intramolecular hydrogen bonding are studied on the basis of solution 13C NMR spectroscopic data and semiempirical MO (AM1) calculations of the r
Coenzyme Model Studies. Part 3. Transimination and Reduction using NADH Models

N-Arylidenealkylamines (1) undergo transimination with aniline derivatives in glacial acetic acid.In the presence of 3,5-bis(ethoxycarbonyl)-2,6-dimethyl-1,4-dihydropyridine (Hantzsch ester) transimination is followed by reduction of the transimination products (3) but not of (1).Transimination also takes place in acetonitrile on treatment of the amines (1) with anilinium trifluoroacetate.These phenomena are analogous to transiminations at the catalytic sites of pyridoxal-dependent enzymes and a similar transimination is followed by reduction in the mechanism of glutamate dehydrogenase.
