Abstract: When being put into CDCl3 (slightly acidic condition), the double bond of steroid drug (LIVIAL) will rearrange 24 hours. This paper shows that the 2D NMR techniques were successfully performed to determine the structures of compound 1 and compound 2. All of the 1H and 13C NNR chemical shifts were assigned by 1D and 2D NMR. Their stereochemistry was discussed, too. The structures of compound 1 and compound 2 were simulated by computer molecular modeling. Their results agree with those of 2D NMR.
