摘要

Schmidt reaction (sodium azide/sulfuric acid) of 1, 5-and of 1, 8-dichloroanthraquinones gives, in each case, both of the theoretically possible lactams (2, 3, 5, 6-dibenzoazepin-4, 7- diones). Two of the four theoretically possible lactams have been identified from Schmidt reaction of 1-and 2-chloroanthraquinones respectively. Methods used include:(a) preferential hydrolysis of one lactam and identification of the isomeric ...
