constructing a Csp3–Csp bond with substituted Hantzsch ester and Meyer nitrile is reported. When benziodoxole-activated alkyne was applied as the alkynyl donor, products containing Csp3–Csp bonds involving primary, secondary, and tertiary carbon centers were achieved in up to 97% yields. K2S2O8 was the optimum radical initiator in this reaction.
报道了用取代的Hantzsch酯和Meyer腈构建C sp3- C sp键的第一个例子。当使用苯并恶唑活化的炔烃作为炔基供体时,含有C sp3- C sp键的伯,仲和叔碳中心的产品收率高达97%。在该反应中,K 2 S 2 O 8是最佳的自由基引发剂。
