1. Synthesis and solid state characterization of molecular rotors with steroidal stators: ethisterone and norethisterone
Braulio Rodrıguez-Molina, Arturo Pozos, Rosa Santillan*. Miguel A. Garcia-Garibay*. Org. Biomol. Chem., 2010, 8, 2993–3000
Molecular rotors prepared by transition metal catalyzed aryl–alkyne coupling reactions using readily available 17α-ethynyl-substituted steroids provide a novel structural platform to explore the dynamics of potential phenylene rotators in the solid state. The steroids selected for this study, ethisterone and norethisterone acetate, are structurally related to testosterone and have been widely studied for their pharmacological activities. Molecular rotors derived from these compounds were prepared by a double Pd(0)-coupling reaction with 1,4-diiodobenzene, or 1,4-dibromobenzene-d4, in yields that varied from ca. 40–75%.
