• Sommario/riassunto: Comprehensive resource exploring a unique chemical transformation that generates new compounds with diverse properties for modern organic synthesis research Denitrogenative Transformation of Nitrogen Heterocycles explores all 10 polynitrogen heterocycles that are known to undergo denitrogenative transformations to date. Following highlights on the remarkable modifications encountered in the synthesis of nitrogen heterocycles, the chapters use a reaction-based approach to explain denitrogenative transformations in detail. This book covers the exponential growth in scientific literature in the last few decades for denitrogenative reactions of polynitrogen heterocycles which play a key role in natural products, medicinal chemistry, pharmaceuticals, biochemistry, and material sciences. This book also discusses denitrogenative cascade reactions, which accomplish powerful transformations from simple polynitrogen heterocycles to more complex molecules in modern synthetic chemistry. Written by a highly qualified academic with significant experience in the field, Denitrogenative Transformation of Nitrogen Heterocycles covers sample topics including: * Transannulation of N -sulfonyl-1, 2, 3-triazoles with polar multiple bonds such as carbonyls and nitriles and non-polar multiple bonds such as alkenes, alkynes, and allenes * Insertion of azavinyl carbenes to C-X/X-X bond, denitrogenative rearrangements of N -sulfonyl-1, 2, 3-triazoles, and denitrogenative transformations of NH- and N -fluoroalkyl-1, 2, 3-triazoles * Metal-catalyzed and metal-free denitrogenative transformations of pyridotriazoles and denitrogenative transannulation of benzotriazoles and thiadiazoles * Denitrogenative transformations of tetrazoles and radical denitrogenative transformations of polynitrogen heterocycles The first book of its kind on the subject, Denitrogenative Transformation of Nitrogen Heterocycles is an essential reference for researchers and scientists working in organic chemistry, organometallic chemistry, and transition metal catalysis, as well as academics and industry professionals in related fields.
