Long-range effect of 17-substituents in 3-oxo steroids on 4,5-double bond hydrogenation
The long-range effect of substituents in the 17-position on the hydrogenation of double bond of the steroidal Δ4-3-ketones in acetic acid on a platinum catalyst is described in a series of testosterone (1) and epitestosterone (5) esters with carboxylic acids of varying alkyl chain length. The ratio 5α-to 5β-products is affected by the nature of substituents in the position 17.

SYNTHESIS OF NEW ANTIATHEROMATOUS DRUGS. STUDY OF THE ESTERIFICATION OF 17β-HYDROXY-5α-ANDROSTAN-3-ONE
The acylation of dihydrotestosterone with propionyl and p-chlorophenoxyisobutyryl chlorides leads to the formation of dihydrotestosterone esters and the 3-enol acylates of the dihydrotestosterone esters.The acid hydrolysis of the 3-enol acylates converts them into the coresponding dihydrotestosterone esters.
