A straightforward, stereospecific and regioselective strategy for the synthesis of substituted E-stilbenes and diarylacetylenes without the use of metal catalysts was developed. DFT calculations were also performed confirming a concerted [4+2] reaction mechanism of the key ring-forming step.
开发了一种直接、立体定向和区域选择性的策略,用于在不使用金属催化剂的情况下合成取代的E-二苯乙烯和二芳基乙炔。还进行了 DFT 计算,确认了关键成环步骤的协同 [4+2] 反应机制。
