We report a general and facile method that provides rapid entry into 3-aryl substituted 4,5,6,7-tetrahydro[1,2,3]triazolo[1,5-a]pyrazines and their ring fused analogues in one-pot under palladium–copper catalysis. The methodology utilises simple and easily available substrates of broad range. The applicability of this reaction for the synthesis of optically active products has been demonstrated. A
我们报告了一种通用且简便的方法,可在一锅中快速进入3-芳基取代的4,5,6,7-四氢[1,2,3]三唑[1,5- a ]吡嗪及其环稠合类似物在钯-铜催化下。该方法利用简单且容易获得的大范围底物。已经证明了该反应在合成光学活性产物中的适用性。还提出了合理的反应机理。
