cross metathesis, to allow the instalment of substituents at the beta position. Subsequent one-pot cyclisation/elimination provides an operationally simple, catalytic and convergent synthesis of 2,4,6-trisubstituted pyridines.
在衍生自交叉复分解的α,β-不饱和δ-磺酰胺基中间体上进行Heck反应,以使取代基安装在β位置。随后的一锅环化/消除提供了2,4,6-三取代吡啶的操作简单,催化和聚合的合成。
