  • Classical Methods in Structure Elucidation of Natural Products

    119,00 €

    The structures of many natural products are given in standard textbooks on organic chemistry as 'established facts'. Yet for those natural products whose structures were determined between 1860 and 1960 by classical chemical methods, the lines of evidence are frequently buried under any number of investigations that led to dead ends and to revised structure assignments. Since very little is known about the structure clarification of these products at present, this volume serves to shed light once again on the achievements of previous generations of chemists, who worked with minimal experimental tools.

    The selection of the 25 representative examples is subjective and arbitrary, dictated by the author's pleasure in recovering fundamental milestones in organic chemistry, with e...
