A series of molecules of therapeutic interest, possessing the new skeleton of 1H-benzo[c]pyrido[2,3,4-kl]acridine with acyl or aminoacyl and methoxy or aminoalkoxy substituents on the aromatic homocycles were synthesized by means of a Friedländer-type reaction. The requisite 5-aminodihydroquinoline-4-ones 1, whose preparation is described, were reacted with the appropriate alpha-tetralones 2 using
通过Friedländer方法合成了一系列具有治疗意义的分子,这些分子具有1H-苯并[c]吡啶基[2,3,4-kl] ac啶的新骨架,芳族同环上具有酰基或氨基酰基以及甲氧基或氨基烷氧基取代基型反应。使用共沸条件下的酸性催化剂(PPTS),将必要的5-氨基二氢喹啉4-ones 1(其制备方法已描述)与适当的α-四氢萘酮2反应。优化的反应时间和产率取决于温度,温度不得低于90摄氏度。
