The hitherto difficult site-selective p-methoxybenzylation of secondary amides using p-methoxybenzylated alkylsilyl peroxides as a novel p-methoxybenzylation agent under copper catalysis is reported. The reaction proceeds under mild reaction conditions in a highly chemoselective manner. This approach was successfully applied to the site-selective p-methoxybenzylation of peptides.

对甲氧基苄基自由基促进的仲烷基酰胺的化学选择性保护

据报道,在铜催化下,使用对甲氧苄基化烷基过氧化物作为新型对甲氧基苄基化试剂,对仲酰胺进行迄今困难的位点选择性对甲氧基苄基化。该反应在温和的反应条件下以高度化学选择性的方式进行。该方法已成功应用于肽的位点选择性对甲氧基苄基化。
