of diaminodienyl diketones la, b has been previously used [i~ 2] to synthesize coumarin derivatives IIa, b, the reaction of which with ammonium acetate gave substituted carbostyrils IIIa, b. The alkylation of the Na salts of the latter with benzyl chloride and N,N-dimethylaminoethyl chloride proceeds at the ring nitrogen atom to give N-alkylcarbostyrils IIIc-e. The compounds that were synthesized by
二氨基二烯基二酮la、b的分子内环化先前已用于[i~2]合成香豆素衍生物IIa、b,其与乙酸铵反应得到取代的喹诺酮IIIa、b。后者的Na盐与苄基氯和N,N-二甲基氨基乙基氯的烷基化在环氮原子处进行,得到N-烷基喹啉IIIc-e。通过该方法合成的化合物在其结构中含有羰基官能团;这确保了它们在 Fischer 反应中使用的可能性,以获得对研究其精神活性感兴趣的含四环吲哚的系统。
