Synthesis of Cyclohexanones by a Tandem Photocatalyzed Annulation

The rapid synthesis of cyclic scaffolds is of high importance to the chemistry community. Strategies for the convergent synthesis of substi-tuted carbocycles and heterocycles remain underexplored despite the plethora of applications that these cyclic motifs have in the phar-maceutical and materials industries. Reported herein is a tandem carbene and photoredox-catalyzed process for the convergent synthesis of substituted cycloalkanones via a formal [5+1] cycloaddition. Featuring two distinct photoredox cycles and a novel α-oxidation of ben-zylic ketones, this reaction offers a mild approach to construct two contiguous C–C bonds and eliminates the need for strong bases or expensive metal catalysts. The utility of this method is highlighted through various product diversification reactions that allow access to a range of important cyclic scaffolds.

Guardianes del mar y del viento. El conflicto socioambiental del pueblo ikoot en el istmo de Tehuantepec

The resistance of some indigenous communities to the global capital extractivist logic has resulted in the development of strategies beyond the economic sphere, beyond market and capital gain; in that sense, it bursts into the territories for the conquest of goods, bodies and rights through biocultural dispossession. In this logic of extra-economic domain, the worldview of the indigenous people who have coevolved with its habitat and the protection of their territories has managed to face the prevailing capitalist system. Our objective is to present an analysis of the community resistance process carried out by the Huave or ikoots community, on the Tehuantepec Isthmus in Oaxaca, Mexico. Through various community strategies, the ikoots have managed to cope with the advancement of mega projects that seek to exploit the potential of the region, due to its geographical potentialities.

Architetture e strategie per il welfare. Il caso di Brunico in Val Pusteria

In both the South Tyrolean and Alpine areas, the case of Brunico is emblematic as regards welfare strategies. From the seventies of the last century and up to today, far-sighted planning policies have contributed decisively to this. The physical and spatial translation of welfare policies and strategies are the numerous architectural and territorial actions that contribute to providing Brunico with an offer of services worthy of a large center. The welfare theme seems to cross across all sectors of society. What is particularly surprising is not only the particular executive and formal quality of the various infrastructures and structures present (and planned) in the municipal area, but also and above all their concentration within such a limited perimeter. Careful and minute planning, together with punctual actions on the territory and the adoption of the competition practice for the assignment of the assignments, all linked by a substantial communion of intent between citizenship, administration and designers, can lead also a mountain city to become competitive in terms of services to the community, strategies and structures for welfare. A possible point of reference for those alpine realities that want to look to the future with a view to regeneration and modernity.

Responses to Apocalypse: Early Christianity and Extinction Rebellion

The Extinction Rebellion (XR) movement has grown rapidly in the past two years. In popular media, XR has sometimes been described using religious terminology. XR has been compared to an eco-cult, a spiritual and cultural movement, and described as holding apocalyptic views. Despite XR lacking the distinctive religiosity of new testament and early (pre-150ACE) Christianity, the movement resonates with the early Christian experience in several ways. (1) A characterization of events within the world as apocalyptic. (2) Both feel vulnerable to the apocalypse in specific ways, though each responds differently. (3) Both experience the apocalypse as a community and develop community strategies in response to the apocalypse. The paper sketches certain features of new testament Christianity and compares some of these to XR. The main difference between the two movements is that XR makes decisions to actively become vulnerable, whereas new testament Christianity was more often passively vulnerable. Elements of new testament Christianity provide a context for understanding XR as a response to an apocalypse.
