    摘要: A steroid comprising a 17-spirolactone or corresponding open lactone structure is obtained by carbonylation of a 17-alkenyl or 17-alkynyl substrate. A 17-alkenyl intermediate may be prepared by semi-hydrogenation of a 17-alkynyl group. Multiple reaction schemes are disclosed for preparation of a 3-keto-9,11-epoxy-17-spirolactone steroid such as eplerenone. Novel intermediates are also disclosed, as well as steps for forming such novel intermediates, or converting them to further intermediates or products, by semi-hydrogenation, carbonylation, 6,7-dehydrogenation, furylation or other transformations or combinations thereof.

    摘要: A digoxin derivative/immunogenic protein conjugate is disclosed which has the carbohydrate moiety of digoxin intact. Antibodies raised against this conjugate show minimal cross-reactivity to digoxin metabolites enabling the use as an antibody in the diagnostic analysis for digoxin when measured in the presence of its metabolites found in serum isolated from a human.
