Developments in the field of stereochemistry began in the nineteenth century. The concept of chirality was first introduced by Jean Baptiste Biot. The present book deals with the major issue that is N-N chiral axis in 3-monoaminoquinazolin-4-(3H)-one, 3-diacylaminoquinazolinones and mono- and di-aniline (DAA and MAA) derivatives. The book presents the how to synthesize and characterize different MAA, DAA, MAQ, and DAQ compounds. Last chapter focus on the chemoselectivity especially competitive reactions of pyrrolidine and piperidine, diethylamine and diphenylamine, ethanolamine and...
