STEROIDS 8 THE DIENONEPHENOL REARRANGEMENT IN THE STEROID SERIES SYNTHESIS OF A NEW CLASS OF ESTROGENS

Abstract

The dienone-phenol rearrangement of the recently described2,10 Î 1,4,6-androstatrien-17-ol-3-one and the corresponding 3,17-dione (XII) produced 1-methyl-Î 6-dehydroestradiol and 1-methyl-Î 6-dehydroestrone (XIII). Dehydrogenation led to the corresponding
