1-(Arylchloromethyl)pyridinium chlorides. Investigation by X-ray single crystal diffraction and semiempirical (PM3, AM1, MNDO) calculations

The molecular structures of l-[chloro(2-methoxyphenyl)methyl]pyridinium chloride and l-[chloro(3-nitrophenyl)methyl]pyridinium chloride were studied by X-ray single crystal diffraction and semiempirical calculations (PM3, AM1, and MNDO) in comparison with

Synthesis of thiazolidine-4-carboxylic acids and N-(1-sulfonatoalkyl)pyridinium betaines from N-(1-chloroalkyl)pyrydinium chlorides

N-(1-chloroalkyl)pyridinium chlorides (1) react with L-cysteine to yield thiazolidine A-carboxylic acids.When salts 1 are not isolated, N-(1-sulfonatoalkyl)pyridinium betaines can be obtained under particular conditions.

AN EXPEDIENT ROUTE TO 1H-BENZIMIDAZOLES AND 1H-IMIDAZOPYRIDINES

1H-Benzimidazoles, 1H-imidazopyridines, and 1H-imidazopyridines can be synthesized readily by reaction of unisolated N-(1-chloroalkyl)pyridinium chlorides with 1,2-benzenediamines, 2,3-pyridinediamine, and 3,4-pyridinediamine, respectively.

A new and convenient method for the preparation of 2-substituted quinazolines

Aldehydes, converted in situ into N-(1-chloroalkyl)pyridinium chlorides using thionyl chloride and pyridine, react with 2-aminobenzylamine, under mild conditions, to yield 1,2,3,4-tetrahydroquinazolines. The latter can be aromatized readily by treatment w

Novel syntheses of heterocycles with N-(1-haloalkyl)azinium halides. Part 2. Preparation of N-unsubstituted 1,4-dihydropyridines

N-(1-Chloroalkyl)pyridinium chlorides, prepared from thionyl chloride, pyridine, and aldehydes, readily react with enaminocarbonyl derivatives to yield 1,4-dihydropyridines under mild and neutral conditions.

Novel synthese of heterocycles with N-(1-haloalkyl)azinium halides. Part 5. Preparation of N-substituted 1,4-dihydropyridines

Thirty N-substituted Hantzsch 1,4-dihydropyridines were prepared under mild and neutral conditions from N-substituted enaminocarbonyl derivatives and aldehydes activated under the form of N-(1-chloroalkyl)pyridinium chlorides by means of thionyl chloride

NOVEL SYNTHESES OF HETEROCYCLES WITH N-(1-HALOALKYL)AZINIUM HALIDES: PART 6. PREPARATION OF 2,3,4,5,10,11-HEXAHYDRO-1H-DIBENZODIAZEPIN-1-ONES

Conversion of aldehydes into N-(1-chloroalkyl)pyridinium chlorides (by means of pyridine and thionyl chloride) and further reaction with 3-(2-aminophenyl)amino-5,5-dimethyl-2-cyclohexenone provide a novel and efficient route to the title compounds.
