cross-coupling of iodinated imidazo[1,2-a]pyridines was performed, permitting the preparation of various vinyl-, ethynyl-, and allenyl-substituted derivatives. These methods are particularly valuable, given their experimental simplicity and high degree of flexibility with regard to functional groups that can be introduced in positions 3, 6, or 8 of the imidazo[1,2-a]pyridine core.

进行了碘化咪唑并[1,2- a ]吡啶的Stille和Sonogashira交叉偶联的系统研究,从而可以制备各种乙烯基,乙炔基和烯基取代的衍生物。这些方法由于它们的实验简单性和对于可以引入到咪唑并[1,2- a ]吡啶核的3、6或8位上的官能团的高度灵活性而特别有价值。对于引入的上述类型的不饱和基团,详细报道了在各种反应条件下有关不同取代位置和2-取代基的性质的影响。
