This book presents Pd- and Ni-catalyzed transformations generating functionalized heterocycles. Transition metal catalysis is at the forefront of synthetic organic chemistry since it offers new and powerful methods to forge carbon–carbon bonds in high atom- and step-economy. In Chapter 1, the author describes a Pd- and Ni-catalyzed cycloisomerization of aryl iodides to alkyl iodides, known as carboiodination. In the context of the Pd-catalyzed variant, the chapter explores the production of enantioenriched carboxamides through diastereoselective Pd-catalyzed carboiodination. It then discusses Ni-catalyzed reactions to generate oxindoles and an enantioselective variant employing a dual ligand system. Chapter 2 introduces readers to a Pd-catalyzed diastereoselective anion-capture cascade. It also examines diastereoselective Pd-catalyzed aryl cyanation to synthesize alkyl nitriles, a method that generates high yields of borylated chromans as a single diastereomer, and highlights its synthetic utility. Lastly, Chapter 3 presents a Pd-catalyzed domino process harnessing carbopalladation, C–H activation and π-system insertion (benzynes and alkynes) to generate spirocycles. It also describes the mechanistic studies performed on these reactions.

Transition-Metal-Catalyzed C-H Functionalization of Heterocycles A comprehensive guide to recent advances in this field Constituting the majority of all known compounds, heterocycles are structures that incorporate one or more heteroatoms within their core, thus exhibiting properties that are quite different from their all-carbon analogs. They are fundamental to all fields of chemistry and, therefore, their synthesis and modification has attracted a great deal of attention in the recent years. In this vein, transition-metal-catalyzed C-H bond functionalization forms a crucial tool for generating and analyzing heterocyclic compounds. Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume Set, showcases diverse C-H functionalization methodologies and their incorporation into the latest research. The chapters serve as an essential tool depicting detailed site-selective functionalization of heterocyclic cores, along with a comprehensive discussion on their mechanistic approaches. Readers of Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume-Set will also find: A detailed introduction to C-H activation along with the mechanistic aspects of transition-metal-catalyzed C-H bond activation reactions Easy-to-use structures with each chapter dedicated to a type of heterocycle and its specific functionalization methodologies A leading team of international authors in C-H bond functionalization Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume-Set is a valuable guide for students and researchers in organic synthesis and process development, in both academic and industrial contexts.

Advances in Transition-Metal Mediated Heterocyclic Synthesis provides an overview of recent catalytic reactions involving transition metals to produce heterocyclic compounds. The book is organized according to the type of transformation used to achieve the synthesis of the heterocyclic systems (mainly aza- and oxa-heterocycles). As such, it covers recent applications on the synthesis of heterocycles, also describing the details of the novel transformations in a didactic manner to motivate readers in search of new catalytic processes. The editors have included state-of-the-art strategies, including transition-metal reactions involving unsaturated systems (reactions of allenes, new gold(I)-catalyzed reactions, and Prins reaction). Chapters highlight the versatility of organopalladium chemistry dealing with carbonylative transformations, C-H activation reactions, coupling processes, and the control of the ambiphilic character of organopalladium species. Finally, the book discusses new reactions leading to heterocycles based on C-H activation processes catalyzed by other metals (Rh, Ru, Co). Written by an outstanding team of authors who are leading experts in organometallic chemistry and organic synthesis, this book is a valuable resource not only for chemists mainly focused on synthesis, but also for those interested in reaction mechanisms involving transition metals. Helpfully organized by transformation type to stimulate the search for new synthetic processes Completely illustrated and written by global experts Includes thoughtfully selected strategies chosen by the editors to exemplify the state-of-the-art of the subject, including transition-metal reactions involving unsaturated systems, organopalladium chemistry, and metal-catalyzed C-H activation

Non-metal catalysis may provide new and green methods for obtaining bioactive heterocycles. Many catalysts contain metals, which can be toxic, energy intensive to remove, and require mining of the source materials. By utilizing metal-free catalysts we avoid these issues. This book explores the use of non-metal catalysts when synthesizing various heterocyclic structures with bioactivity.
