This thesis presents a general approach to accessing nitrogen-substituted hetero- and carbocycles. In short, the annulation reactions developed in the thesis make it possible to access nitrogen-substituted four-, five- and six-membered rings, all essential building blocks for the synthesis of bioactive molecules. Many natural products display a saturated polycyclic core allowing a well-defined arrangement of functional groups in space. As such, they can interact with biological targets with a high degree of affinity and selectivity, surpassing many synthetic drugs. Nevertheless, the efficient synthesis of such complex ring systems poses a challenge for organic chemistry. Through careful tuning of the electronic properties of a nitrogen donor group and a diester acceptor group, the first [3+2] annulation reaction between aminocyclopropanes and enol ethers or carbonyl compounds is now possible. The reaction proceeded under mild catalytic conditions, and the building blocks obtained can be found at the core of bioactive alkaloids, drugs such as Ramipril and biomolecules such as DNA and RNA. Thanks to the dynamic kinetic asymmetric annulation of aminocyclopropanes with enol ethers and aldehydes, access to enantioenriched compounds is also now possible. Lastly, a synthesis of donor-acceptor aminocyclobutanes via [2+2] cycloaddition using a cheap iron catalyst was developed, allowing them to be used in [4+2] annulations to access cyclohexylamines.

This book has been written to ensure that it will be of benefit to industrial analysts.

Globalization and industrialization involve a number of reactions, products, extractions, and separations that require the use of organic solvents. These solvents are responsible for a number of ecological concerns, including atmospheric and land toxicity. Conventional organic solvents are regarded as volatile organic compounds; some are even limited due to their potential for ozone layer depletion. While supercritical liquids exhibit physical properties that could make them ideal substitutes for these volatile compounds, there is particular interest in the use of carbon dioxide as a solvent of crude material. In particular, carbon dioxide has apparent 'green' properties, like its noncombustible nature, the fact that it is generally nonpoisonous, and its relative inertness. Thus, the use of supercritical carbon dioxide can provide practical improvements to the sustainability of industrial products and processes. This book provides in-depth literature in the area of industrial green processes, focusing on the separation, purification, and extraction of compounds utilizing supercritical carbon dioxide as a green solvent.

Wild fruits play an important role in mitigating hunger in the developing world. As a sustainable and natural food source in rural areas, these fruits have a strong effect on regional food security and poverty alleviation. This makes the utilization of wild foods incredibly important for native populations both in terms of food security and economics. There are many traditional methods for wild fruit harvesting, indigenous tree and plant domestication and cultivation passed down through generations that are sustainable and economically viable, ultimately contributing to a better quality of life for large sections of the developing world. To date there has not been a reference work focusing on the full scope of wild fruits from their growth and chemical makeup to their harvest, distribution, health effects and beyond. Wild Fruits: Composition, Nutritional Value and Products adequately fills this gap, expansively covering the utilization of multi-purpose wild fruits in regions worldwide. Effects on quality of life, food security, economics and health are extensively covered. Over 31 wild fruit species are examined, with individual chapters focusing on each species' phytochemical constituents, bioactive compounds, traditional and medicinal uses and chemical composition. Harvest, post-harvest and consumption methods are covered for each, as are their overall effect on the food security and economics of their native regions. This book is essential for researchers in search of a comprehensive singular source for the chemical makeups and cultivation of indigenous wild fruits and their many benefits to their native regions.

Written by the founder of the field of carbon "quantum" dots (carbon dots) and related technology, this book outlines the principles of carbon dots and presents strong evidence for that small carbon nanoparticles and by extension carbon dots represent the nanoscale carbon allotrope at zero-dimension.

This unique and timely text is designed to help food science students learn to perform critical analysis of food processing technology and consider the incorporation of elements that touch on contemporary technological developments in the food sector. As the food industry adjusts to new consumer demands for safe and low processed foods, the time has come to harmonize product and process engineering with 'relationship engineering' from farm to fork. This increasingly allows the opportunity for food sector professionals to consider the existence of new drivers of food consumption. These newly discovered drivers are explored in great detail over the course of this book from industrial, economic and human resource viewpoints. Social Drivers In Food Technology presents a series of helpful case studies are presented covering six important food sectors: chocolate, coffee, yogurt, juice, baby food and snacks. These cases have been chosen in order to illustrate dynamic and innovative advances in food processing technology. The information provided over the course of this book has been gained through the thorough study of both scientific literature and organizational reports from food processing companies. The major economic aspects related to food technology are also outlined throughout the text. This multidisciplinary approach is motivated by the opportunity to contextualize the technological debate in strategy and organizational economics, contributing to the formation of human resources. This text is informed by the concept that one must look beyond the technology of the food processing sector and discuss opportunities that involve re-thinking product innovation and process, knowledge generation and human resource training. These innovations have been highlighted in food science & technology literature, but their economic and managerial implications have remained unexplored until now. With its informative case studies, helpful illustrations and quizzes and comprehensive, well-organized scope, Social Drivers In Food Technology is a much-needed textbook that will allow students to look at food processing technology from both industrial and economic perspectives and to consider the important human resource elements involved.
