Article	Year
Synthesis of 4- and 16 alpha-hydroxylated equine estrogens. Steroids, 1990, Volume: 55, Issue:6 4-Hydroxyequilin, 4-hydroxyequilenin, and 16 alpha-hydroxyequilenin were synthesized as authentic specimens for the metabolic studies of equine estrogens. The synthetic route leading to the 4-hydroxylated compounds was started from o-vanillin, which was transformed into the beta-ketosulfoxide (2b) by sequential multistep reactions. This was converted to the alpha,beta-unsaturated ketone (3) as Michael acceptor. Condensation of 3 with 2-methylcyclopentane-1,3-dione, followed by ring closure with methanesulfonic acid provided the cyclized estrapentaene (5). Several oxidoreduction reactions were then performed to give the desired compounds. Preparation of 16 alpha-hydroxyequilenin was attained by reductive cleavage of the 16 alpha,17 alpha-epoxide formed from equilenin.
