trifluoride etherate and 90% hydrogen peroxide (2:1–4:1 complex) has been found to be a useful reagent for promoting the benzylic hydroperoxide rearrangement of readily oxidizable substrates bearing a free, basic amine. The use of this procedure for introduction of the C-4 phenol of the C-4/C-5 selectively-protected -catechol unit found in PDE-I and PDE-II, naturally-occurring phosphodiesterase inhibitors
已发现一种预先形成的,老化的,衍生自三氟化硼醚化物和90%过氧化氢(2:1-4:1配合物)的试剂,对于促进带有游离碱性胺的易氧化底物的苄基氢过氧化物重排是有用的试剂。使用此程序引入在PDE-I和PDE-II中发现的C-4 / C-5选择性保护的邻苯二酚单元的C-4苯酚,这是天然存在的构成磷酸酯中和右旋的磷酸二酯酶抑制剂详细介绍了抗肿瘤抗生素CC-1065的各个部分。
