β-氧代二硫代酸酯在铜催化苯并[ e ]吡唑并[1,5- c ] [1,3]噻嗪衍生物的合成中的双重作用
摘要:
通过β-氧二硫代酯(ODEs)与3-(2-)的串联乌尔曼偶联反应,已经开发出一种简便高效的化学选择性合成苯并[ e ]吡唑并[1,5- c ] [1,3]噻嗪衍生物的方法。溴芳基)-1 H-吡唑以C–S键形成方式,其中ODE既充当底物又充当配体。在NaOH的存在下,在80°C的CH 3 CN中,以CuI为铜源,以良好的收率提供了一系列苯并[ e ]吡唑并[1,5- c ] [1,3]噻嗪衍生物。N 2气氛。

[RhCp*Cl2]2-catalyzed oxidative coupling of 5-aryl-1H-pyrazoles with alkynes and acrylates has been achieved using Cu(OAc)2 as an oxidant. Coupling with alkynes afforded six-membered azacycles as a result of C–C and C–N coupling. Coupling with acrylates followed a process of diolefination and a subsequent aza-Michael cyclization.
