Here we demonstrate the synthesis of various derivatives of 5-(6-substituted phenyl-2H-chromen-3-yl)-
oxazoles 5(a-k) by using Suzuki coupling conditions with different substituted boronic acids and obtained 23-57 % yields.
We also synthesised various derivatives of the 5-(substituted 2H-chromen-3-yl)-oxazoles 3(a-j) mediated by TOSMIC as
a reagent and achieved 58-70 % yield.
在此,我们展示了通过Suzuki偶联条件,使用不同的取代硼酸合成5-(6-取代苯基-2H-色烯-3-基)-噁唑衍生物5(a-k),产率介于23-57%之间。我们还通过TOSMIC作为试剂,合成了5-(取代2H-色烯-3-基)-噁唑衍生物3(a-j),产率达到了58-70%。
