“…We also investigated chemical oxygenation using the Fe III (PA) 3 /H 2 O 2 /CH 3 CN system [18][19][20] for comparison with the electrochemical reaction, and the results are summarized in Table 2. In runs 5 and 6, the allylic hydroxylated products were formed with a-preference, but with significant amounts of ketones.…”

“…[15][16][17] We have been developing a 7a-hydroxylation system for steroids, [18][19][20] and we reported in a preceding paper that the combination of electrolysis and the Fe III (PA) 3 /O 2 /CH 3 CN system gave good results in the hydroxylation of cholesteryl acetate. 21) On the other hand, functionalization, especially oxygenation, of octahydronaphthalenes or decalin derivatives is also very important because many bioactive or natural compounds contain a skeleton resembling the AB fused ring of cholesterol.…”

“…[21][22][23] A useful technique for the catalytic hydrogenation of unsaturated steroids in a microwave oven using ammonium formate as a hydrogen source, has been described. 24 Studies have continued on the allylic oxidation of D 5 -steroids by reagents such as pyridinium fluorochromate, 25 tert-butyl hydroperoxide and a copper catalyst, 26 hydrogen peroxide and a ferric picolinate catalyst, 27 and cumene hydroperoxide and a ferric porphyrin catalyst. 28 The products that were formed from the reaction of cholesterol with the superoxide ion under protic and aprotic conditions have been examined 29 whilst the role of additional ligands in metalloporphyrin catalysed oxidation using molecular oxygen has been noted.…”
