New Regiospecific Synthesis of 2-Trifluoromethyl-1,5 Diazapentadiene Compounds and of 2-Trifluoromethylquinolines, Their Cyclization Products
摘要:
2-Trifluoromethylquinolines 5 are synthesized in high yields using a perfluoroalkylated gemiodoacetoxy derivative 3 and arylamines 4. The intermediate of this reaction, 2-trifluoromethyl-1,5-diazapentadiene compound 6, was isolated. The procedures are easy, and yields are in general high. This sequence represents a valuable new synthesis of substituted 2-trifluoromethylquinolines and of 2-trifluoromethyl-diazapentadienes (vinamidine compounds).

in the presence of phosphoryl trichloride, the resulting 4-anilino-1,1,1-trifluorobut-3-en-2-ones undergo an N → ortho shift of the side chain followed by cyclization and dehydration to afford 2-(trifluoromethyl)quinolines.
