Grignon-Dubois, Micheline published the artcileConvenient synthesis of (trichloromethyl)dihydroquinolines and -isoquinolines, SDS of cas: 606-55-3, the publication is Synthesis (1994), 800-4, database is CAplus.
The reaction of a series of N-alkylquinolinium and N-alkylisoquinolinium iodides towards sodium trichloroacetate in acetonitrile has been investigated under reflux or ultrasonication. In all cases, addition of trichloromethyl anion was observed, and trichloromethyldihydroquinoline or -isoquinoline derivatives were obtained in good yields. Depending on the activation process, addition occurred at the 2- or the 4-position with quinolines and at the 1-position with isoquinolines.
Synthesis published new progress about 606-55-3. 606-55-3 belongs to iodides-buliding-blocks, auxiliary class Quinoline,Salt, name is 1-Ethyl-2-methylquinolin-1-ium iodide, and the molecular formula is C12H14IN, SDS of cas: 606-55-3.
