Selective and efficient structural elaboration of 2-(trifluoromethyl)quinolinones

The acid-catalyzed cyclization-condensation between anilines and ethyl 4,4,4-trifluoroacetoacetate affords 1,4-dihydro-2-trifluoromethyl-4H-4-quinolinones (1), which can easily be converted into 4-bromo-2-(trifluoromethyl)quinolines. These undergo halogen/metal exchange, generating 2-trifluoromethyl-4-quinolyllithiums, when treated with butyllithium, and hydrogen/metal exchange, generating 4-bromo-2-trifluoromethyl-3-quinolyllithiums, when treated with lithium diisopropylamide. Trapping of the latter intermediates provides 3-functionalized products that may be further elaborated by electrophilic substitution of the bromine atom. A few unexpected findings resulted from these investigations, the most noteworthy being an unprecedented buttressing effect and a counterintuitive halogen reactivity. ( Wiley-VCH Verlag GmbH & Co.

Preparation of 2-trifluoromethyl cinchoninic acids
-
, (2008/06/13)
2-Trifluoromethyl cinchoninic acids can be prepared in high yields by reaction of an alkali metal 2-aminophenylglyoxylate and 1,1,1-trifluoroacetone in the presence of a weak acid and a metal salt of a weak acid. Preferably reaction is effected by first h
