A novel procedure has been developed for the regioselective hydroxylation of ring-C aromatic diterpenoids via their (η6-arene)tricarbonylchromium(0) complexes. Lithiation-cupration-oxidation gives good yields from methoxyarene complexes having an unhindered ortho position.
一种新颖的过程已经经由被开发用于环-C的芳族二
萜类化合物的区域选择性羟化它们的(η 6 -arene)tricarbonylchromium(0)配合物。
锂化-杯化-氧化可从邻位不受阻碍的甲氧基
芳烃配合物中获得良好的收率。
