摘要

Abstract. Derivatives of cyanimidocarbonic acid 1 react with ethyl y-bromoacetoacetate to ethyl thiazolylacetates 2 which are converted into 7-hydroxythiazolo [4, 6-b] pyrid-5-ones 3 by acid or base catalyzed cyclisation. These compounds can be alkylated as well as acylated. The 7-liydroxy group is exchangeable for chlorine. Furthermore in position G electrophilic sulfonation can take place.
