Mild, metal-free, highly regioselective hypervalent-iodine mediated C-2 acetoxylation and C-3 oxidations of N-substituted indoles with (diacetoxyiodo)benzene [PhI(OAc)2] have been reported. The reaction involves three cascade steps. The quantity of PhI(OAc)2 employed in this reaction plays a key role in the outcome of three types of products (2a–4a). Furthermore, the mild and highly regioselective C-2
已经报道了轻度,无金属,高区域选择性的高价碘介导的C-2乙酰氧基化和N-取代的吲哚与(二乙酰氧基碘)苯[PhI(OAc)2 ]的C-3氧化。该反应涉及三个级联步骤。在该反应中使用的PhI(OAc)2的量在三种类型的产物(2a - 4a)的结果中起关键作用。此外,已经开发了用PhICl 2对N-取代的吲哚进行温和且高度区域选择性的C-2氧化和C-3二氯化。广泛的研究,包括原位红外技术和H 2 O 18进行标记实验以了解可能的反应机理。
