Kolev (Institute of Organic Chemistry, Bulgarian Academy of Sciences, Bulgaria) reports on recent research in amino acid amides. He offers a conformational and structural investigation of hydrochlorides, hydrogensquarates, and ester amides of squaric acid of the following amino acids: alanine, arginine, isoleucine, leucine, methionine, phenylalanine, threonine, tryptophan, tyrosine, prolin, serine, and valine. Theoretical results are compared with experimental results obtained by single crystal X-ray diffraction in order to explain the role of intra- and intermolecular hydrogen bonds on the conformational preference in solid-state as compared to gas phase data. The author also describes the solid-state IR-LD spectra of samples of the various compounds studied as suspensions in nematic liquid crystal. Color and b&w chemical illustrations and charts are included. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
