This book includes three chapters (from chapter III-V). Chapter I and II are already published under the title ¿An overview of indazoles and its synthetic intermediates¿.Chapter III describes the synthesis of pyrazolo and isoxazolo fused derivatives of 7,8,9-trihydropyrazolo[4,5-b]carbazol-6(3H)-one and 9-benzyl-7,8-dihydropyrazolo[4,5-b]azacarbazol 6(3H)-one. Chapter IV is concerned with the synthesis of pyrimidine ring incorporated derivatives of 7,8, 9-trihydropyrazolo[4,5-b]carbazol-6(3H)-one from oxo-ketenedithioacetals, chalcones, dimethylamino methylene ketones and enolic ethers of carbazole annulated pyrazoles. Chapter V is related with the synthesis of benzodiazepino, benzothiazepino and quinolino condensed 7,8,9-trihydropyrazolo[4,5 b]carbazol-6(3H)-one and 9-benzyl 7,8-dihydropyrazolo[4, 5-b]-9-azacarbazol-6(3H)-one from oxo-ketenedithioacetals and chalcones derived from carbazolo annulated pyrazole and azacarbazolo annulated carbazole.

This book focuses on the new and old methods for the synthesis of various heterocycles using Lawesson¿s reagent. The book covers an important and rapidly growing branch of heterocyclic chemistry and can serve as a guide to those who are completing their education and are about to enter the job market. Students will be able to find all Lawesson¿s reagent-assisted protocols for the synthesis of heterocycles in one place. This feature of the book provides an important benefit, because sometimes users want to see all the possibilities and relevant information for making a particular compound using one particular reagent. The purpose of this valuable resource is to provide the knowledge not only to students but also to pharmacologists, biochemists, organic and medicinal chemists, researchers, and academic professionals for easy access to synthetic protocols for different heterocycles using Lawesson¿s reagent. The book will be greatly helpful for everyone involved in the field and can pave the way for better understanding and quantification of heterocycle synthesis.
