Synthesis of Hetero-cyclic compounds for Bio-medical Applications

Focusing on synthetic and spectral studies, this book explores the conversion of substituted 2-aminobenzenethiols into various compounds, including phenothiazines and benzothiazines. It details the oxidation behavior of 4H-1,4-benzothiazines and the synthesis of substituted phenoxazines. Methods such as alkaline hydrolysis and Smiles rearrangement are employed, highlighting reactions with o-halonitrobenzenes and beta-diketones. The text also covers the preparation of trithenodithiazin-3-ones, emphasizing the intricate chemical processes involved in these transformations.
