A convenient high yield synthetic route leading to 2,9-diacyl-1,10-phenanthrolines has been developed. The reaction of bis-amide 1 with 2-pyridyllithium, 6-bromo-2-pyridyllithium or 2-thienyllithium led to the diacyl compounds 5,6 and 7, respectively. Attempts to prepare 8 by intramolecular coupling of 6 or by treatment of 1 with dilithio analogue 9b were unsuccessful. Treatment of 1 with butyllithium
已经开发了导致2,9-二酰基-1,10-菲咯啉的方便的高产率合成路线。双酰胺1与2-吡啶基锂,6-溴-2-吡啶基锂或2-噻吩基锂的反应分别产生二酰基化合物5,6和7。通过分子内偶联6或通过用二硫代类似物9b处理1来制备8的尝试均未成功。用丁基锂或芳基锂试剂处理1得到10a,10b和10c。
