, p. 383 - 386 (2007/10/03)
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.
A new and convenient method for the preparation of 2-substituted quinazolines
Vanden Eynde,Godin,Mayence,Maquestiau,Anders
, p. 867 - 869 (2007/10/02)
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 synthese of heterocycles with N-(1-haloalkyl)azinium halides. Part 5. Preparation of N-substituted 1,4-dihydropyridines
Vanden Eynde,Mayence,Maquestiau,Anders
, p. 3291 - 3304 (2007/10/02)
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
