A clean, facile and practical synthesis of α-oxoketene S,S-acetals in water has been developed. Catalyzed by tetrabutylammonium bromide (TBAB) at room temperature in water, a range of β-dicarbonyl compounds have been converted to the corresponding α-oxoketene S,S-acetals in very high yields. The catalyst in the aqueous phase can be recycled after the separation of organic products.
已经开发了在水中清洁,方便且实用的α-氧杂环丁烯S,S-缩醛的合成方法。在室温下于水中由溴化四丁基铵(TBAB)催化,已将一系列β-二羰基化合物以非常高的收率转化为相应的α-氧杂环丁烯S,S-缩醛。在分离有机产物之后,可以将水相中的催化剂再循环。
