摘要：

Enolised alpha-thiocyanato-beta-dicarbonyl compounds dimerise in ethanol at room temperature to give tautomeric 4,5-disubstituted 2-amino- and 2-acetamido-thiazoles by a C-S-C + C-N cyclisation. Tautomerism is due to the unusual 4-(beta-dicarbonyl-alpha-thio) substituent. Competing intramolecular cyclisations lead to minor amounts of heterocycles containing the thiazole and/or oxathiole ring systems.
