标 题 :Process for the preparation of 14beta-hydroxy - 17 -keto - 15 - androstenes and novel intermediates produced thereby
发明人：AFONSO ADRIANO
权利人:SCHERING CORP
摘要:14B-HYDROPEROXY-15-ANDROSTEN-17-ONES, PREPARED BY THE ACTION OF OXYGEN ON 14-ANDROSTEN-17-ONES, UPON TREATMENT WITH A MILD REDUCING AGENT YEILDS 14B-HYDROXY-15ANDROSTEN-17-ONES, USEFUL INTERMEDIATES IN THE SYNTHESIS OF STERODIAL CARDENOLIDES. PREFERRED SPECIES ARE 14 B-HYDROPEROXY-5A-15 ANDROSTEN3B-OL-17-ONE 3-ACETATE AND THE 5B-EPIMER THEREOF (PREPARED BY THE ACTION OF OXYGEN OR 5A-14-ANDROSTEN-3B-OL17-ONE 3-ACETATE AND THE 5B-EPIMER THEREOF, RESPECTIVELY) EACH OF WHICH, UPON MILD REDUCTION, PREFERABLY WITH TRIETHYL PHOSPHITE, YEILDS 14B-HYDROXY-5A-15-ANDROSTEN-3BOL-17-ONE 3-ACETATE AND THE 5B-EPIMER THEROF, RESPECTIVELY, WHICH ARE USEFUL INTERMEDIATES IN THE SYNTHESIS OF UZARIGENIN AND DIGITOXIGENIN, RESPECTIVELY.
