Phosphole sulfide 1 undergoes cycloaddition to give a new 15-phosphasteroid. The 13C-NMR and 2JPC-coupling constants of several compounds prepared similarly are discussed, permitting structure assignment to one of the 7-phosphabicyclo[2.2.1]heptane adduct 5. Thiophosgene reacts with the PS moiety of 1, giving 12 after hydrolysis, through a PS to PO transformation coupled in case of 1 with a proton
