Triazole-Directed Pd-Catalyzed C(sp2)–H Oxygenation of Arenes and Alkenes [PDF]
Selective Pd-catalyzed C(sp2)–H oxygenation of 4-substituted 1,2,3-triazoles is described. Unlike previous metal-catalyzed C–H functionalization events, which preferentially occur at the activated heterocyclic C–H bond, the regioselective oxygenation of ...

A connection between the Ghirlanda--Guerra identities and ultrametricity [PDF]
We consider a symmetric positive definite weakly exchangeable infinite random matrix and show that, under the technical condition that its elements take a finite number of values, the Ghirlanda--Guerra identities imply ultrametricity.Comment: Published ...

ABSTRACT Background Patients with high‐risk neuroblastoma who either are refractory to induction chemotherapy or relapse following multi‐modal treatment have a dismal prognosis. Based on data from the BEACON trial, since 2021 the UK national guidelines recommend bevacizumab, irinotecan, and temozolomide (BIT) for patients with relapsed/refractory ...

Directed nickel-catalyzed regio- and diastereoselective arylamination of unactivated alkenes
Few methods exist to add a carbon and nitrogen atom across an unfunctionalized alkene. Here the authors show a method to regio- and diastereoselectively add aryl and amino groups to terminal and internal alkenes, via nickel catalysis and a removable ...
