Complete 1H and 13C NMR spectral assignment of 17-hydroxy epimeric sterols with planar A or A and B rings.

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).

PREPARATION OF UNLABELLED AND 3H>-LABELLED EPITESTOSTERONE AND ITS METABOLITES

Cold as well as 3H>-labelled substrates and metabolites IX-XI, XV, XVI, XX-XXII, XXIV, XXV and XXVIII were prepared by catalytic hydrogenation of epitestosterone (VIII) and Λ1-dehydroepitestosterone (XIII).The key step in the preparation of compound XXVIII was reaction of 3β-tosylates XXVI and XXX with potassium nitrite in dimethyl sulfoxide.
