Abstract

Abstract Aus 1, 2-Ethandithiol (1) und den β-Dicarbonylverbindungen 2 werden die 1, 3- Dithiolane 3 erhalten, die regioselektiven Reaktionen an der noch freien Carbonylfunktion zugänglich sind. So lassen sich die Derivate der β-Ketocarbonsäureester zu den Carbonsäuren 4 hydrolysieren, die bei der Veresterung mit den Alkanolen 5 die estergruppenmodifizierten 1, 3-Dithiolane 3 liefern. Einwirkung von Trimethyloxonium- ...
