consisted of using ground plant roots as starting material in gossypol Schiff base semisynthesis, we now report how this concept can be used to access enantiomerically pure Schiff base atropisomer derivatives of gossypol in only two steps. This study has been envisioned since enantiomerically pure Schiff base atropisomer derivatives of gossypol are generally more potent biologically when compared to racemic

synthesized via an in situ procedure in high yields. Structural data showed that all target compounds exist as the enamine tautomer. Bioassays showed that several compounds exhibited cytotoxic effects against three human cancer cell lines. Compound 8a showed the greatest cytotoxic effect againsthepatocellularcarcinoma (HepG2), lung carcinoma (LU-1), and breast cancer (MCF-7) cell lines with IC50 values
