“…Bisdehydrodoisynolic acid (127, R = H), one of the most potent estrogens, was discovered by Miescher and co-workers [84,85] as a degradation product of equilenin. In a brilliant series of papers [86][87][88][89][90][91][92][93][94] they also described the total synthesis of this compound (Scheme 3-11).…”

“…(25) To us, the proposed formulation did not appear very likely and we decided to reinvestigate the carboxylic acids obtained from estrogenic hormones. We first prepared marrianolic acid (II) (14) and bisdehydromarrianolic acid (12) from estrone and equilenin by oxidation with hypoiodite. A study of their reactions simplified the elucidation of the corresponding monocarboxylic acids.…”
