Originally discovered in 17(3-hydroxy-20-ketosteroids, but thoroughly studied in the 17a-hydroxy-20-keto series, this reaction involves an acid- or base-catalyzed acyloin rearrangement which yields a 6-membered D-ring ... [Pg.219]

Deoxygenation." The 17a-hydroxy group of 17a,21-dihydroxy-20-ketosteroids is selectively reduced by ISi(CH,), in CH,CN at room temperature (equation I). A free 21-hydroxyl group is necessary for this dehydroxylation. [Pg.262]
