Synthesis and characterization of new tail-to-tail dimers of bile acids with different spacers, in Proceedings of the 13th International Electronic Conference on Synthetic Organic Chemistry, 1–30 November 2009, MDPI: Basel, Switzerland, doi:10.3390/ecsoc-13-002563-906980-23-5http://hdl.handle.net/10347/26860The 13th International Electronic Conference on Synthetic Organic Chemistry session Polymer and Supramolecular ChemistryNew 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 spacerseng© 2009 The author(s). Published by MDPI, Basel, Switzerland.
