Abstract: | Complete 1H and 13C spectral assignments of 17beta- and 17alpha-hydroxy epimers of three biologically active sterols (boldenone, 3-methoxyestradiol and 3-methoxydihydroequilenin) were achieved making use of one- and two-dimensional NMR techniques (1D-HOHAHA, DEPT, COSY, NOESY, TOCSY, HSQC and COLOC). |
