Conformationally Locked Pyramidality Explains the Diastereoselectivity in the Methylation of trans-Fused Butyrolactones
2020
A stereoselectivity model inspired by the total synthesis of stemona alkaloids is developed to explain why enolate-derived 3,4-fused butyrolactones are methylated with a preference for syn alkylation. The model shows how conformational locking present in nonplanar enolate structures favors syn over anti methylation, due to less significant structural distortions in the syn pathway. The developed model was also successfully used to rationalize selectivities of previously documented methylation reactions. peerReviewed

Veniet Tempus (QNat.7.25): Stoic Philosophy and Roman Genealogy in Seneca's View of Scientific Progress
2014
Seneca's views on the future development of knowledge have often been interpreted as an enlightened anticipation of the modern faith in progress. And Seneca himself has been depicted as a sort of Condorcet avant la lettre. In the present paper, I argue that while it is extremely interesting to investigate the reception of Senecan patterns in modern thought, the writer's idea of scientific and moral enhancement should primarily be understood in the intellectual and socio-anthropological framework of ancient culture. Indeed, a reassessment of the evidence offered by the Natural Questions and the Moral Epistles shows that Seneca devises a broadly conceived spectrum of progress, which reflects …
Commune Ius Animantium (Clem. 1.18.2): Seneca's Naturalism and the Problem of Animal Rights
2013
The present paper focuses on an intriguing passage of Seneca's treatise 'On Clemency' (De Clementia) dealing with the topic of human and animal rights (1.18.1-2). This is the only passage in which the Latin philosopher employs the juridically and philosophically significant expression 'commune ius animantium', thus referring to a form of nature-based 'animal right'. In Seneca's words, there would be a common right of living beings forbidding to perpetrate certain acts of violence. On the whole, however, the passage seems to aim at maintaining the inviolability of human rights, paying special attention to the pitiful condition of slaves. Given the presence of such a man-centered context, sch…
Vox Naturae: The Myth of Animal Nature in the Latin Roman Republic
2016
The paper examines the representation of animals as embodiment of nature in the culture of the late Roman republic. By discussing a selection of passages from Sallust, Cicero and Lucretius in conjunction with other Greek and Latin sources, the paper shows that the typically Western myth of 'animal nature' - the cultural belief that animal mirror a perennial state of nature, as opposed to human society - played a very important role in the ethical debate of the first century BC and took in this period a form which was bound to influence the centuries to come.
Pictures of Nature. Mineral Imagery in Modern French Aesthetics
2016
Thus, from antiquity to the twentieth century, figured stones have changed so many times their ontological status. They were considered collectibles, emblems of prodigiousness or of curiosity; they have been interpreted as works of art attributed to nature or to a supreme creator, in competition with the works of the artists; they were finally gazed at as case or guardians of a secret revealed in the underground and overt (at the meantime) „stone writing”. This study is devoted to the forms of mineral imagery. It is interested in enlightening the contacts between visual arts and arts of speech, between sensitive image and immaterial images, and the difficult journeys, and the indispensable …
