The unexpected results of the cyclization reactions of N,N′-bis(oxotrifluoroalkenyl)-1,3-phenylenediamines [1,3-C6H4-(NHCRCHC(O)CF3)2], where R = H, Me, and Ph, in a strongly acidic medium (PPA), allowing the synthesis of new trifluoromethylated heterocycles containing the 1,7-phenanthroline nucleus in 32–40% yields and 7-aminoquinolines (38–40% yields), is reported. The bis-enaminoketone intermediates
N,N'-双(氧代三氟烯基)-1,3-苯二胺[1,3-C 6 H 4-(NHCR CHC(O)CF 3)2 ]的环化反应的出乎意料的结果,其中R = H,据报道,Me和Ph在强酸性介质(PPA)中可以合成新的含1,7-菲咯啉核的三氟甲基化杂环,产率为32–40%,而7-氨基喹啉(产率为38–40%)。在温和条件下,很容易从4-烷氧基-4-烷基(芳基)-1,1,1-三氟烷-3-烯-2-酮与1,3-苯二胺的反应中分离出双烯酮中间体( 68–86%的产量)。

This paper reports interesting results of the conventional synthesis of a new series of 2,10-dialkyl(aryl)-4,8-bis(trifluoromethyl)-1,7-phenanthrolines, in 22-40% yields, from cyclization reactions of N,N'-bis(oxotrifluoroalkenyl)-1,3-phenylenediamines [1,3-C6H4-(NHCR=CHC(O)CF3)(2)] in a strongly acidic medium (PPA) and absence of solvent. The synthetic route also allowed the isolation of a new series of 2-alkyl(aryl/heteroaryl)-4-trifluoromethyl-7-aminoquinolines, in 20-73% yields, simultaneously. The enaminone precursors were obtained from the reaction of 4-alkoxy-1,1,1-trifluoroalk-3-en-2-ones [CF3C(O)CH=C(R)OR1, where R = H, Me, Ph, 4-MePh, 4-OMePh, 4-ClPh, 4-FPh, 4-BrPh, 4-NO2Ph, 2-furyl and R-1 = Me, Et] with 1,3-phenylenediamine under mild conditions, in 47-91% yields.
