Sanders, Georgine M.; Van Dijk, M.; Van der Plas, H. C. published the artcile< Reactions of haloquinolizinium bromides with diethylamine>, Recommanded Product: Methyl 3-bromo-2-pyridinecarboxylate, the main research area is quinolizinium bromide diethylamine reaction.
The reactions of quinolizinium bromide (QB) and its four monobromo derivatives with diethylamine have been investigated. For Br in position 2 or 4, substitution is the main process, whereas for Br in positions 1 and 3 quant. ring opening is found. The substituted pyridylbutadienes formed by ring opening, are cis-trans-butadienes, which isomerize into the all-trans forms. The steric course of the ring opening is explained.
Journal of Heterocyclic Chemistry published new progress about 53636-56-9. 53636-56-9 belongs to class pyridine-derivatives, and the molecular formula is C7H6BrNO2, Recommanded Product: Methyl 3-bromo-2-pyridinecarboxylate.
