Mild oxidation of bromides by iodine(III) reagents generated active electrophilic bromination species that were reacted with polyprenoids. By simple and minor variations of an I(III)/Br combination, the reactivity could be selectively steered toward dibromination, oxybromination, or bromocyclization, giving access to a wide array of brominated motifs.
碘(III)试剂对溴化物的轻度氧化产生了活性的亲电子溴化物质,该物质与聚异戊二烯反应。通过对I(III)/ Br组合进行简单和较小的变化,可以选择性地将反应性转向二溴化,氧溴化或溴环化,从而获得广泛的溴化基序。
