This is the second volume of a first-of-its-kind four-volume book set that provides readers with up-to-date information on α-amino acids, the potential challenges in working with α-amino acids, the protecting groups for the carboxyl, amino and side chain groups of the amino acids, and the most popular heterocyclic compounds that are originating from alpha-amino acids. These heterocyclic compounds include hydantoins, thiohydantoins (including 2-thiohydantoins, 4-thiohydantoins, 2,4-dithiohydantoins), 2,5-diketopiperazines, N-carboxyanhydrides, N-thiocarboxyanhydrides, sydnones, sydnonimines, azlactones, pseudoazlactones, and oxazolidin-5-ones. This is the first resource to comprehensively collect all the heterocycles that can be directly prepared from α-amino acids. In addition, almost all kinds of synthetic methods for a particular type of heterocycles from alpha-amino acids are included, along with the detailed mechanistic discussions and experimental procedures. In Volume 2: Hydantoins, Thiohydantoins, and 2,5-Diketopiperazines compiles the three IUPAC accepted nomenclature systems for heterocyclic compounds, which will be very useful for readers working in the heterocyclic chemistry field for giving synthesized molecules their correct names. In addition, three groups of heterocyclic compounds, i.e., hydantoins, thiohydantoins (including 2-thiohydantoin, 4-thiohydantoin and 2,4-dithiohydantoin), and 2,5-diketopiperazines, have been organized with updated literature information. Particularly, all three groups of heterocyclic compounds have demonstrated many important biological activities, particularly anticancer and antibacterial activities. On the other hand, these three groups of heterocycles can be applied as substrates to make other chemical derivatives, particularly novel unnatural amino acids. All their reactivities have been compiled and updated. The other volumes include: Volume 1: Protecting Groups Volume 3: N-Carboxyanhydrides, N-Thiocarboxyanhydrides, and Sydnones Volume 4: Azlactones and Oxazolidin-5-ones All together, this unique 4-volume set thoroughly covers the two types of heterocyclic compounds that are originated from alpha-amino acids, providing carefully compiled updated information with detailed examples. The author has shared many thoughtful insights based on his strong background in physical organic chemistry. The volumes will be highly valuable for graduate students and senior students, as well as for professors and researchers working in the field of medicinal and pharmaceutical chemistry, organic chemistry, organic synthesis, heterocycles, and proteins and peptides.

Explanation of the structure-property relationship of a given molecule is generally simple because the characteristics of the atomic groups and chemical bonds and the effects emerging from their interaction have long been known, both from theore- cal studies and numerous experimental results. In contrast, it is often difficult to analyze, estimate, and account for the structure-properties relationship in sup- molecules. The characteristics of supramolecules are governed both by the nature of the constituent molecules and by their configuration while the characteristics of the constituent molecules are usually evident as mentioned above; their configu- tions are difficult to control, predict, and accurately estimate because of insufficient knowledge regarding the intermolecular forces. Moreover, since most of the int- molecular forces constructing supramolecules are weak, the supramolecular str- ture may vary depending on various factors, such as modification of the molecular structure, auxiliaries, and experimental conditions. Thus, in order to obtain supramolecules with the desired structures and properties, theoretical investigations on the intermolecular forces and accumulation of experimental studies on the re- tionship between the supramolecular structure and properties are both important.
