RT Book,_Section T1 Synthesis and characterization of new tail-to-tail dimers of bile acids with different spacers A1 Antelo Queijo, Álvaro A1 Álvarez Alcalde, María de las Mercedes A1 Jover Ramos, Aida A1 Meijide del Río, Francisco Ángel A1 Vázquez Tato, José AB New dimeric steroid-based surfactants derived from 3α,7α,12α-trihydroxy-5β- cholan-24-amine (steroid residue) and isophthalic acid, 5,5'-biisobenzofuran-1,1',3,3'- carboxylic acid and succinic acid (spacers) were synthesized and structurally characterized by NMR techniques. The first spacer was also employed to synthesize the dimer corresponding to the 3α,12α-dihydroxy-5β-cholan-24-amine residue. In all cases the steroid residues are tail-to-tail linked through amide bonds with the spacers PB MDPI SN 3-906980-23-5 YR 2009 FD 2009 LK http://hdl.handle.net/10347/26860 UL http://hdl.handle.net/10347/26860 LA eng NO Vázquez Tato, J.; Meijide, F.; Jover, A.; Álvarez Alcalde, M.; Antelo, Á.
