Abstract:

The reactions of 6-vitro-2-trifluoromethylchromone with benzylamine, ethanolamine, and aniline afforded 3-benzyl(2-hydroxyethyl,phenyl)amino-4,4,4-trifluoro-1-(2-hydroxy-5-nitr ophenyl)but-2-en-1-ones, respectively, whereas the reactions with ethylenediamine and diethylenetriamine gave rise to 5-(2-hydroxy-5-nitrophenyl)-7-trifluoromethyl-2,3-dihydro-1H-1,4-diazepi ne and 5-(2-hydroxy-5-nitrophenyl)-7-trifluoromethyl-1,4,8-triazabicyclo{[}5.3, 0]dec-4-ene, respectively. Morpholine added at the double bond of 2-trifluoromethyl- and 6-nitro-2-trifluoromethylchromones to form 2-morpholino-2-trifluoromethylchroman-4-one and its 6-nitro-substituted analog, respectively, whereas piperidine reacted only with 2-trifluoromethylchromone to yield 2-piperidino-2-trifluoromethylchroman-4-one.
