A highly efficient oxidative-coupling reaction between diarylpropargylic sp(3) C-H and active methylenic sp(3) C-H was achieved with DDQ as oxidant. The reaction afforded a direct method for the propargylation of 1,3-dicarbonyl compounds, thus providing a concise synthesis of the corresponding products.
以DDQ作为氧化剂,实现了二芳基炔丙基sp(3) C-H与活性亚甲基sp(3) C-H之间的高效氧化偶联反应。该反应为1,3-二羰基化合物的炔丙基化提供了一种直接方法,从而为相应产物提供了简洁的合成路线。
