Abstract

Abstract Die Schmidt-Reaktion an 1-Thio-chromanonen-(4)(1) führt in Abhängigkeit von den Substituenten am Benzolring zu 1.4-und/oder 1.5-Benzothiazepinonen (2 bzw. 4), wobei Elektronenacceptoren die Wanderung der Arylgruppe begünstigen. 1-Thio-chromanon-(4)- S. S-dioxide (5) ergeben mit Stickstoffwasserstoffsäure ausschließlich 1.5-Benzothiazepin- Derivate (6).
