A new 3β-chlorine steroids derivative of 25R-3β-chlorine-furosta-5,20(22)-dien-26-ol (1) was synthesized in which 3-methoxydiosgenin (3) of both rings, E and F, were opened under the influence of ammonium chloride in acetic anhydride. The structure of 1 was determined by 1H, 13C NMR, IR, MS spectra, and X-ray diffraction. The mechanism for forming the new compound 1 has been briefly explored.
