Direct Diels‐Alder Reaction of Biomass‐Derived Furfurol with Maleimides in a Bio‐Based Green Solvent

open access: yesEuropean Journal of Organic Chemistry, Volume 27, Issue 15, April 15, 2024.
The upconversion of biomass‐derived furfurol through a direct Diels‐Alder reaction with maleimides in 2‐Me‐THF enabled the construction of various heterocyclic compounds, while switching the reaction selectivity depending on the temperature. Abstract Environmental concern has motivated an inclination to exploit waste and upgrade it into high‐added ...

Organocatalytic Synthesis of Thiiranes from Alkenes

open access: yesAnnalen der Pharmacie, 2022
Thiiranes, the corresponding sulfur analogues of epoxides, are less studied and less encountered in literature. This might be due to the limited existing synthetic approaches for their synthesis.

Apollo a simposio. Gli inni simposiali tra skolia e peani

open access: yes, 2022
As Alcman also adfirms (PMG 98), symposia were normally opened by a paean in honour of Apollo. Hence derives the Alexandrian practice of opening the collections of sympotic poetry with a hymn to the gods (mainly Apollo, but other gods may also appear). The aim of this contribution is examining the hymns to Apollo included in the Theognidean Sylloge (ll.
