The book "Synthetic Studies of C-15 and C-17 Compounds" by Manasi Singhi offers a comprehensive analysis and innovative approaches to the synthesis of specific chemical compounds. It addresses the development of new synthesis methods for various coumarins and their derivatives, which are produced through the condensation of substituted o-hydroxyacetophenones and 2'-hydroxychalcones with phenylacetic acid or its derivatives. The methods presented are characterized by their efficiency and the yields achieved, making them of great interest to professionals in chemical research. Furthermore, spectroscopic studies, particularly 13C-NMR, are discussed for the characterization of the compounds, highlighting the relevance of theoretical foundations in practical applications. This specialist book is a valuable resource for students and professionals engaged in organic chemistry and the synthesis of complex molecules.
