Silver-catalysed hydroamination: synthesis of functionalised pyrroles
摘要:
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 (60s). (C) 2004 Elsevier Ltd. All rights reserved.
