Abstract
The invention is drawn to 17-oxo-15,16-seco-19-nor steroids which are useful as intermediates in the production of various 15,16-seco-19-nor progestins. These progestins display elevated progestational activity with a minimum of ancillary hormonal activity and are thus useful in the suppression of ovulation in the human female.
