Author Description

<p>This is the third 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 α-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 α-amino acids are included, along with the detailed mechanistic discussions and experimental procedures.</p><p>Volume 3: N-Carboxyanhydrides, N-Thiocarboxyanhydrides, and Sydnones presents up-to-date detailed information on two types of heterocyclic compounds that originate from alpha-amino acids: NCAs/NTAs and sydnones/sydnonimines. The volume also covers the more than 10 initiating systems for NCA monomers to undergo the ring-opening polymerization, which are very useful for the readers in order to make living polypeptides/polypeptoids. In addition, the method to characterize these prepared polypeptides/polypeptoids is also included. Particularly, two modern mass spectrometric techniques (MALDI-TOF and ESI-TOF) have been explained with detailed examples, where the elucidation of molecular weight of protein based on the ESI-TOF spectra has been given with a practical example as well as the theory that it is based on, a unique feature of the volume.</p><p>The other volumes in the set are:</p><p>Volume 1: Protecting Groups</p><p>Volume 2: Hydantoins, Thiohydantoins, and 2,5-Diketopiperazines</p><p>Volume 4: Azlacton
