Yang, Yiwen published the artcileConvenient synthesis of 2-aryl-1-haloindolizines from pyridinium salts and 2-aryl-1,1-dihaloalk-1-enes, Recommanded Product: 1-(Cyanomethyl)pyridin-1-ium chloride, the publication is Synthesis (2011), 3447-3452, database is CAplus.
2-Aryl-1-haloindolizines were synthesized from pyridinium salts and 2-aryl-1,1-dihaloalk-1-enes using a DBU/THF system. 2-Aryl-1,1-dihaloalk-1-enes containing electron-withdrawing or -donating groups were efficiently converted into the corresponding 2-aryl-1-haloindolizines in moderate to excellent yields.
Synthesis published new progress about 17281-59-3. 17281-59-3 belongs to pyridine-derivatives, auxiliary class Pyridine,Nitrile,Salt, name is 1-(Cyanomethyl)pyridin-1-ium chloride, and the molecular formula is C8H19NO2, Recommanded Product: 1-(Cyanomethyl)pyridin-1-ium chloride.
