oxidation of p-cresol with tert-butyl hydroperoxide, in hexafluoro-2-propanol/toluene gave toluquinone efficiently. The reaction can be applied to the regio-selective short-step syntheses of vitamin K3 and vitamin K1 from p-cresol.
BF 3 ·OET 2 -催化的甲基迁移4-甲基-4-叔-butyldioxycyclohexadienone,其通过的钌催化氧化获得p甲酚与叔丁基过氧化氢,在六氟-2-丙醇/甲苯,得到有效甲苯醌。该反应可以应用于维生素K的区域选择性短步合成3和维生素K 1从p甲酚。
