  structure) hydroxylates phenols with O2 via a stable side‐on peroxide complex, which is similar to the active site of tyrosinase in terms of the ligand environment and its spectroscopic properties. The catalytic oxidation of phenols to quinones proceeds at room temperature in the presence of NEt3 and even non‐native substrates can be oxidized catalytically. The reaction mechanism is analogous to that

• An expedient one-pot entry to catecholestrogens and other catechol compounds via IBX-mediated phenolic oxygenation

  日期：2005.5

  A one-pot procedure for the preparation of catecholestrogens in over 90% yield is reported, involving oxygenation of 17β-estradiol or estrone with o-iodoxybenzoic acid (IBX) followed by reduction with methanolic NaBH4. The procedure, which was extended to the o-hydroxylation of a number of representative phenols in good-to-high yields, expands significantly the scope of phenolic oxidation mediated by IBX. © 2005 Elsevier Ltd.
