benzothiazoles or benzoxazoles is reported. This represents a first example of metal-catalyzed decarboxylative C–H heteroarylation of benzo-fused heterocycles. The transformation provides a convenient route, with good yields and functional group tolerance, to various important arylheteroaryl and unsymmetrical biheteroaryl structural motifs.
报道了(杂)芳基羧酸与苯并噻唑或苯并恶唑的钴催化的脱羧交叉偶联反应。这代表了金属催化的苯并稠合杂环的脱羧CH杂杂芳基化反应的第一个例子。该转化为各种重要的芳基杂芳基和不对称的双杂芳基结构基序提供了一条方便的途径,具有良好的收率和官能团耐受性。
