Heterocyclic compounds are organic compounds containing at least one atom of carbon, and at least one element other than carbon, such as sulphur, oxygen or nitrogen within a ring structure. These structures may comprise either simple aromatic rings or non-aromatic rings. Some examples are pyridine (C5H5N), pyrimidine (C4H4N2) and dioxane (C4H8O2). Many heterocyclic compounds, including some amines, are carcinogenic. This book details the proposed mechanisms of Gewald-like reactions and the wide scope of substituted 2-aminothiophenes for real life applications. Literary information about synthesis methods, structure, physical-chemical and biological properties is summarised, and also information about conversion of adamantyl-1 and adamantyl-2 imidazole and benzimidazole derivatives is given. In addition, 3-acetylindole derivatives have been in the centre of attention of researchers over many years due to the high practical value of these compounds. This book presents a survey of the literature on 3-acetylindoles chemistry and provides useful and up-to-date data for medicinal chemists.

Extensive experimentation and high failure rates are a well-recognised downside to the drug discovery process, with the resultant high levels of inefficiency and waste producing a negative environmental impact. Sustainable and Green Approaches in Medicinal Chemistry reveals how medicinal and green chemistry can work together to directly address this issue. After providing essential context to the growth of green chemistry in relation to drug discovery in Part 1, the book goes on to identify a broad range of practical methods and synthesis techniques in Part 2. Part 3 reveals how medicinal chemistry techniques can be used to improve efficiency, mitigate failure and increase the environmental benignity of the entire drug discovery process, whilst Parts 4 and 5 discuss natural products and microwave-induced chemistry. Finally, the role of computers in drug discovery is explored in Part 6. - Identifies novel and cost effective green medicinal chemistry approaches for improved efficiency and sustainability - Reflects on techniques for a broad range of compounds and materials - Highlights sustainable and green chemistry pathways for molecular synthesis
