Zur Synthese von 3‐Amino‐naphth[c]isothiazolen

Abstract: 3‐Amino‐naphthonitril‐(2) 7 kann durch Spaltung von 4‐Carboxymethyl‐mercapto‐benzo[g]chinazolin 6 in wäßrigem Medium bei pH = 9 in guten Ausbeuten erhalten werden. 1‐Amino‐naphthonitril‐(2) 11 ist mit Hilfe der Bedford‐Partridge‐Reaktion (Isatinoxim‐Thermolyse) aus 1H‐Benz[g]indolin‐2,3‐dion‐3‐oxim 13 leicht zugänglich. Es werden Synthesewege für die Vorstufen der Aminonitrile 7 und 11 angegeben sowie Untersuchungen zum Anwendungsbereich der BEDFORD‐PARTRIDGE‐Reaktion und der Spaltung der substituierten 4‐Merc… Show more

“…The authors were apparently unaware that this compound was first prepared almost 40 years ago by reaction between 1-naphthylamine and ethoxymethyl- eneurethane, although no spectroscopic details are given in this earlier work. 77, 78 Samoquasine A showed significant cytotoxicity against murine lymphoma L1210 cells (IC 50 0.38 µg cm Ϫ3 ).…”
