La reconstrucción del castillo-palacio de Monteagudo en la segunda mitad del siglo XVIII

Francisco Magallón y Beaumont, V marqués de San Adrián –abuelo del famoso marqués retratado por Goya–, asumió en 1753 una herencia prácticamente arruinada, entre la que se contaba el castillo-palacio de Monteagudo. Tras años de abandono en los que ni había sido habitado ni se había efectuado reforma alguna, estaba a punto de desplomarse. Esta forta- leza representaba el señorío jurisdiccional de los Magallón sobre la villa, de ahí que el marqués decidiese reconstruirlo, gastando en ello considerables cantidades de dinero. El encargado del proyecto fue José Marzal y Gil, el mejor arquitecto de la zona, y las obras se desarrollaron aproximadamente entre 1766 y 1777.Francisco Magallón y Beaumont, Vth marquis of San Adrián –grandfather of the famous marquis painted by Goya–, received in 1753 a bankruptcy heri- tage. One of the properties he inherited was the Monteagudo castle. After years abandoned and ignored, when no one lived in, the castle threatened to collapse. The fortress represented the feudal domain of the Magallón's on Monteagudo. That is the reason why the Vth marquis of San Adrián spent important amounts of money in the reconstruction of the building. The architect Jose Marzal y Gil, the better in the area, was in charge of the project and the works took place between 1766 and 1777

Synthesis of γ-, δ-, and ε-Lactams by Asymmetric Transfer Hydrogenation of N-(tert-Butylsulfinyl)iminoesters

Highly enantiomerically enriched γ- and δ-lactams have been prepared by a simple and very efficient procedure that involves the asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters followed by desulfinylation of the nitrogen atom and spontaneous cyclization to the desired lactams during the basic workup procedure. Five- and six-membered ring lactams bearing aromatic, heteroaromatic, and aliphatic substituents have been obtained in very high yields and ee’s up to >99%. A slight modification of the procedure also allowed the preparation of ε-lactams in good yields and very high enantioselectivities. Both enantiomers of the final lactams could be prepared with equal efficiency by changing the absolute configuration of the sulfinyl chiral auxiliary

New insights into the neolithisation process in southwest Europe according to spatial density analysis from calibrated radiocarbon dates

The agricultural way of life spreads throughout Europe via two main routes: the Danube corridor and the Mediterranean basin. Current archaeological literature describes the arrival to the Western Mediterranean as a rapid process which involves both demic and cultural models, and in this regard, the dispersal movement has been investigated using mathematical models, where the key factors are time and space. In this work, we have created a compilation of all available radiocarbon dates for the whole of Iberia, in order to draw a chronological series of maps to illustrate temporal and spatial patterns in the neolithisation process. The maps were prepared by calculating the calibrated 14C date probability density curves, as a proxy to show the spatial dynamics of the last hunter-gatherers and first farmers. Several scholars have pointed out problems linked with the variability of samples, such as the overrepresentation of some sites, the degree of regional research, the nature of the dated samples and above all the archaeological context, but we are confident that the selected dates, after applying some filters and statistical protocols, constitute a good way to approach settlement spatial patterns in Iberia at the time of the neolithisation process
