A new synthesis in the isoquinoline series is discussed: the reaction of appropriate benzamides and oxalyl chloride affords isoquinolinetriones along N-aroyloxamoyl chlorides. The solvent effect, the acid catalysis and the isomer distribution are accounted for. On the other hand 1 - hydroxy - 3 - oxoisoindoline - 1 - carboxylates may be obtained by acid-catalyzed ring closure of N-aroyloxamates. Both
讨论了异喹啉系列的新合成方法:适当的苯甲酰胺和草酰氯的反应可沿着N-芳酰基草酰氯生成异喹啉三酮。考虑了溶剂效应,酸催化作用和异构体分布。另一方面,可以通过酸催化N-芳酰基草酸酯的闭环获得1-羟基-3-氧代异吲哚啉-1-羧酸酯。两个环化都需要一个激活基团。
