Abstract
The reactions between -hydroxylphenyl-functionalized enaminones and sulfonyl hydrazines providing 3-sulfenylated chromones via domino chromone ring construction and C(sp)-H bond sulfenylation have been achieved under transition-metal-free conditions by using KIO as the only catalyst.
摘要
在无过渡金属条件下，以KIO作为唯一催化剂，实现了α-羟基苯基官能化烯胺酮与磺酰肼之间的反应，通过多米诺色酮环构建和C(sp)-H键亚磺酰化反应生成3-亚磺酰化色酮。
