Abstract

Abstract 2-Aryl-4-methylthiazol-5-carbonsäurecchloride 3a–g bilden mit Diazomethan im Überschuß 2-Aryl-5-diazoacetyl-4-methylthiazole 4a–g als Hauptprodukte und daneben in geringen Mengen Chlorketone 5a–g. Die Bromketene 6a–f ergeben mit Thio-und Allylthioharnstoff die Bithiazolyle 7a–f sowie 8a–c, e und f. Nach der Methode von Wolfrom wurden die Ketone 9a–g dargestellt.
