Die Verwandlung der senecanischen Tragödie in Marc-Antoine Murets “Julius Caesar” und Jacques Grévins “César”

1994

In 1547 Marc-Antoine Muret wroteJulius Caesar, the first tragedy by a French author with an exclusively historical plot. While imitating the dramatic structure of Seneca's tragedies, he fundamentally changed the nature of the tragic conflict, transferring it from the character of the tragic hero to the clash of two basically positive principles, monarchy and Republican liberty. Muret's Caesar does not plan a revengeful crime as the Senecan heroes did; he is rather the successful statesman, ready to die after having won the victory over the entire world, and his apotheosis is soon fulfilled by the gods. On the other side are the Republican heroes Brutus and Cassius who succeed in killing the…

Memories, forgetting and silences in the museographical proposal of the memory center “La Perla”

2019

El artículo analiza el proceso de selección y consagración de memorias en un caso particular: el del Espacio para la Memoria que funciona en lo que durante la última dictadura en Argentina (1976-1983) fue el Centro Clandestino de Detención (CCD) conocido como “La Perla” en la provincia de Córdoba, Argentina. El mismo analiza las funciones que fue asumiendo el lugar: CCD, cuartel militar, espacio de memorias, y los valores que diferentes grupos y el estado le adjudicaron a lo largo de su historia. A partir de allí, aborda las propuestas elaboradas para su institucionalización como espacio de memoria, la elaboración del guion del museo de sitio y las muestras exhibidas, profundizando en el ju…

The title compound, C27H33NO5, obtained from diethyl ether, crystallizes in space group P2(1) with four molecules in the asymmetric unit. The dioxinone and imide rings are almost planar, whereas the cyclohexane and cyclohexene rings form distorted conformations. The crystal structure confirms an earlier proposal about the stereoselectivity of Diels - Alder reactions to spirocyclic chiral 1,3- dienes.

Thermische Diels-Alder-Reaktionen mitN-(2-Alkenoyl)-(S)-prolinestern als chiralen Dienophilen in organischen und wäßrigen Reaktionsmedien

1990

Thermal Diels-Alder Reactions with N-(2-Alkenoyl)-(S)-proline Esters as Chiral Dienophiles Cyclopentadiene reacts with N-acryloyl-(S)-proline benzyl and allyl ester in toluene at 0°C to give the bicycloheptene-carboxylic acid amides with a stereoselection of (2S):(2R) = 81:19. In the reactions with the N,N′-fumaroylbis(proline esters) the cycloadducts are formed in high yields and with isomer ratios of up to 97:3. The absolute configuration of N,N′-〈(1R,2R,3R,4S)-bicyclo[2.2.1]hept-5-ene-2,3-diyldicarbonyl〉bis-[(S)-proline benzyl ester] (6 a) has been determined by an X-ray analysis. In the reactions of the acrylamides with cyclopentadiene and of the fumaramides with cyclopentadiene, isopre…

A PM3 study of the molecular mechanism for the cycloaddition between cyclopentadiene and protonated pyridine-imine derivatives

2001

Abstract The molecular mechanism of the cycloaddition reaction between cyclopentadiene (CP) and three pyridine-imine derivatives has been studied by means of PM3 semiempirical method. The role of the protonation, endo/exo and π-facial stereoselectivity are analyzed and discussed. In neutral conditions the cycloaddition between CP and the pyridine-imine takes place along a concerted mechanism. Protonation on both nitrogen atoms brings out that the reaction pathway takes with a very low barrier along a stepwise mechanism. PM3 results are capable to find the key factors governing this chemical reaction and to explain the experimental outcome.
