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 diethanolamine, succinimide and
phthalimide with DAQs and competitive reaction of pyrrolidine and
piperidine with diacylaniline derivatives and acetyl chloride. The
density functional and time dependent density functional theories have
been applied and discussed the N-N bond as chiral axis, electronic,
spectroscopic data.
