| Abstract: | Abstract A new mestranol acetate, 17α-ethinyl-17-hydroxy-3-methoxyestra-1,3,5(10)-triene-6-one-17-acetate, was synthesized by an efficient
three-step sequence starting from norethindrone. The structure of the new steroid was characterized by 1H NMR, 13C NMR, MS, IR spectrum and X-ray single crystal diffraction. It crystallizes in the triclinic system, space group P1. The
molecules are arranged in a head-to-tail fashion without intra- and intermolecular hydrogen bonding. |
