Transition metal-diene complexes in organic synthesis - 13. Highly Chemo- and Stereoselective Oxidations of Tricarbonyliron-Cyclohexadiene Complexes: Synthesis of 4-Deoxycarbazomycin B
Chemo- and stereoselectivity in oxidations of tricarbonyl[5-aryl-η4-cyclohexa-1,3-diene]iron complexes is achieved by the choice of the oxidizing reagent. This procedure provides iron-complexed 4a,9a-dihydro-9H-carbazoles, 4b,8a-dihydrocarbazol-3-ones, and 4-deoxycarbazomycin B.
