End-stage renal disease patients require peritoneal dialysis (PD) as a life-saving therapy; however, they continue to experience systemic inflammation and increased cardiovascular pathology. These complications can be exacerbated by exposure to PD solutions (PDS) containing glucose. This highlights the clinical unmet need for novel osmotic agents to replace glucose. Here, we tested troxerutin, an FDA-approved drug, as a potential osmotic agent.

Synthesis of Multisubstituted Pyridines by Heterocyclization of TosMIC Derivatives: Total Synthesis of Caerulomycins A and K

José A. García-García, José Luis Aceña, Patricia García-García, David Sucunza*

A concise synthesis of multisubstituted pyridines from α-allylic TosMIC derivatives and electrophiles is reported. The process involves a tandem heterocyclization exploiting the dual reactivity of the isocyanide group. The methodology tolerates various electrophiles, including halogen sources, and proceeds under mild conditions. Its utility is showcased in the total synthesis of caerulomycins A and K, in only five steps from TosMIC.

Selective Construction of Diverse Polycyclic Compounds by Electrophilic Cyclizations of Biaryl-Embedded 1,7-Enynes

Lucía Sánchez-Jiménez, Patricia García-García, Manuel Á. Fernández-Rodríguez*

Electrophilic cyclizations of biaryl-embedded 1,7-enynes enable the selective synthesis of dibenzofused polycycles with diverse topologies. The outcome strongly depends on the promoter—gold(I) complexes, Brønsted acids, or electrophilic boron reagents—as well as the substitution pattern of the enyne. This Account highlights recent advances and establishes a basis for future developments through the controlled design of substrates and activation modes.
