title: Practical one-pot conversion of 17beta-estradiol to 10beta-hydroxy- (p-quinol) and 10beta-chloro-17beta-hydroxyestra-1,4-dien-3-one.
abstract: An efficient one-pot procedure for the preparation of 10beta,17beta-dihydroxyestra-1,4-dien-3-one (p-quinol, 1, 75%) is reported, involving oxidation of 17beta-estradiol with potassium permanganate. Similar treatment of 17beta-estradiol with sodium chlorite led to 10beta-chloro-17beta-hydroxyestra-1,4-dien-3-one (2) in 44% yield along with smaller amounts 4-chloro-10beta,17beta-dihydroxyestra-1,4-dien-3-one (3), 2,10beta-dichloro-17beta-hydroxyestra-1,4-dien-3-one (4), and 4,10beta-dichloro-17beta-hydroxyestra-1,4-dien-3-one (5).
