Popis: | It has been shown that functionalised pyrroles can be efficiently prepared using a two-step sequence. This sequence involves the propargylation of secondary enaminones using n-BuLi and propargyl bromide, followed by intramolecular hydroamination catalysed by silver nitrate. The hydroamination can be carried out at room temperature (overnight) or in a domestic microwave oven (60 s). |
