Steroid hormones and analogs part 2 synthesis of racemic 18 homo 9 iso b norestrone 3 methyl ether racemic 18 homo 8 iso b nor 19 nortestosterone and racemic 18 homo b nor 19 nor retro testosterone



Steroid hormones and analogs part 2 synthesis of racemic 18 homo 9 iso b norestrone 3 methyl ether racemic 18 homo 8 iso b nor 19 nortestosterone and racemic 18 homo b nor 19 nor retro testosterone



Indian Journal of Chemistry Section B Organic Chemistry Including Medicinal Chemistry 15(7): 585-588



(.+-.)-18-Homo-B-noroestrone 3-methylether and (.+-.)-18-homo-9-iso-B-noroestrone 3-methylether were prepared from 3-methoxy-18-homo-B-noroestra-1,3,5(10),8-tetraen-17.beta.-ol. The production of the 2 isomers under different conditions of metal-ammonia reduction was attributed to differences in the protonation of the anion radical or the dianion. The synthesis of .+-.)-18-homo-8-iso-B-nor-19-nortestosterone and (.+-.)-18-homo-B-nor-19-nor-retro-testosterone is described.
