Reduction of steroidal ketones with aminoiminomethanesulphinic acid
Abstract
Some representative oxo-steroids were treated with aminoiminomethanesulphinic acid and the products were analysed by g.l.c. The 3- and 6-ketones were reduced; 20-ketones did not react. The results indicated that the reducing agent favours back-side attack. The olefinic double bond of cholest-4-en-3-one is reduced before the oxo-group is affected.
