摘要:
O-(Nitroaryl)oximes of variously substituted 3-keto steroids in which the aryl ring is in turn substituted in the ortho and/or para position with nitro groups are antilittering, anabolic and androgenic agents.
摘要:
17 Beta -Hydroxy-17 Alpha -ethynyl steroids are converted to 17-ethers and 17-esters of 17 Alpha -hydroxy-20-keto-pregnane steroids by forming a 17-sulfite ester of the 17 Beta -hydroxy group with thionyl chloride in the presence of base and then reacting the sulfite ester with an alcohol or carboxylic acid in the presence of an Hg salt.
摘要:
A PROCESS FOR PREPARING 9,11-DICHLORO STEROIDS WHICH INVOLVES THE STEP OF TREATING A 9A-UNSUBSTITUTED-11B-HYDROXY STEROID WITH THIONYL CHLORIDE AND CHLORINE OPTIONALLY IN INERT LIQUID REACTION MEDIA CONTAINING A TERTIARY AMINE. THE 9,11-DICHLORO STEROID PRODUCTS ARE KNOWN, USEFUL ANTI-INFLAMMATORY AGENTS.
摘要:
Steroids having a multiple carbon-carbon bond which is isolated or conjugated with an aromatic ring and which are hydrogenatable to a mixture of stereoisomers are stereo-specifically and selectively reduced by electrocatalytic hydrogenation in an acidic solvent employing a cathode whose surface is a finely divided metal hydrogenation catalyst, such as Raney nickel or palladium.
