New N-alkyl(aryl)-2,4-diaryl-1H-pyrrol-3-ol derivatives have been synthesized in moderate to good yields in a novel and efficient process by aldol reaction of 1-(4-methoxyphenyl)propan-2-ones with phenylglyoxal in the presence of DABCO in water, followed by Paal–Knorr reaction with amines in the presence of a catalytic amount of p-TSA in toluene at reflux.
新的N-烷基(芳基)-2,4-二芳基-1H-吡咯-3-醇衍生物已通过1-(4-甲氧基苯基)丙烷-2的羟醛反应以新颖有效的方法以中等至良好的收率合成。在水中存在DABCO时与苯乙二醛反应,然后在催化下在甲苯中催化量的p -TSA存在下与胺进行Paal-Knorr反应。
