摘要

Abstract Recently reported [1] syntheses of 6-methyl-1, 2, 4, 5-tetrahydro-1, 4-dioxo-3H [1, 2] diazepino [5, 6-b] indole (5) and 4-hydroxy-6-methyl-3H [1, 2] diazepino [5, 6-b] indole (12) were reinvestigated and shown to be in error. The correct assignments for these respective structures are 3-amino-1, 9-dihydro-9-methyl-2H-pyrido [4, 3-b] indol-2, 4 (3H)-dione (6) and 3-amino-3, 9-dihydro-9-methyl-2H-pyrido [4, 3-b] indol-2-one (13). Condensation of 6 and ...
