as a synthon of nitriles, and subsequent coupling with arenes such as N-sulfinylimines and benzimidates bearing a functionalizable directing group provided facile access to two classes of quinazolines under Co(III)-catalysis.
芳烃的C–H活化已被确定为通过
芳烃与不饱和偶联伙伴之间的环化进行杂环合成的重要策略。然而,腈未能充当这样的偶联伴侣。二
恶唑酮已被用作腈的合成子,并且随后与带有功能性导向基团的
芳烃如N-亚磺
酰亚胺和苯甲二胺偶合,提供了在Co(III)催化下容易接近两类
喹唑啉的途径。
