A newsynthesis of oxindoles (8) isoquinolones (5) and benzazepinones (10) by the intramolecular amidoalkylation of aromatic amides of bismethoxycarbonylaminoacetic acid (4, 7, 9) is described.
Die Einwirkung von Oxalylchlorid auf N‐Hydroxymethyl‐benzamid (4) führt zu N‐Benzoyl‐1,3‐oxazolidin‐4,5‐dion (8), wenn man den entstehenden Chlorwasserstoff mittels Zugabe von Kalium‐carbonat oder Durchleiten von Stickstoff entfernt. Anderenfalls bildet sich unter Abspaltung von Chlorwasserstoff, Kohlenmonoxid und ‐dioxid N‐Chlormethyl‐benzamid (6). – Chloral‐ oder Bromal‐acylamide 10 und Oxalylchlorid
relationship of this compound. Growth inhibitoryactivity of CGK733 and novel 35 analogs against HeLa S3 cells was evaluated, and the structure-activity relationship revealed that analogs with the 2-naphthyl or 4-fluorophenyl group instead of the benzhydryl group have activity comparable to CGK733 and that the 3-nitro group on the aniline moiety significantly affects the activity.
