Book Description
Agust Nieto-Galan argues that chemistry in the twentieth century was deeply and profoundly political. Far from existing in a distinct public sphere, chemical knowledge was applied in ways that created strong links with industrial and military projects, and national rivalries and international endeavours, that materially shaped the living conditions of millions of citizens. It is within this framework that Nieto-Galan analyses how Spanish chemists became powerful ideological agents in different political contexts, from liberal to dictatorial regimes, throughout the century. He unveils chemists' position of power in Spain, their place in international scientific networks, and their engagement in fierce ideological battles in an age of extremes. Shared discourses between chemistry and liberalism, war, totalitarianism, religion, and diplomacy, he argues, led to advancements in both fields.

Book Description
Molecular rearrangements occupy center stage in the development of organic synthesis and, consequently, in the impressive achievements that have resulted in the total synthesis of many complex natural products in the last decades. The purpose of this chapter, in this volume of a book series dedicated to the Studies in Natural Product Chemistry, is to show a set of selected and organized molecular rearrangements based on a personal choice of expertise related to the synthesis of complex bioactive molecules. Our selection addresses [3,3]-sigmatropic rearrangements, which continue to provide excellent opportunities for reaching high chemical diversity, operating in efficient synthetic schemes. [3,3]-Sigmatropic rearrangements, such as the Cope and Claisen rearrangements, are among the most basic and useful transformations in synthetic organic chemistry. This is possibly due to the fact that these rearrangements are efficient methods for the synthesis of quaternary, sterically hindered chiral centers, and for the stereoselective formation of carbon–carbon and carbon–heteroatom bonds. In addition, [3,3]-sigmatropic rearrangements can be easily integrated in, and adapted to, cascade processes as a simple method to prepare complex molecules in atom-efficient reactions. Consequently, in the context of [3,3]-sigmatropic rearrangements, we focus on the transformations of propargylic esters, whose rearrangements, in different experimental conditions, have been largely exploited for the synthesis of interesting key and useful intermediates. The rearrangements can be promoted by protic acids, Lewis acids, and noble metals such as Pt, Au, or Cu salts, or complexes that have recently emerged as the most popular and potent electrophilic activators of alkynes toward a number of nucleophilic agents, under homogeneous conditions.
