Design and Synthesis of C4‐Symmetric Axially Chiral β‐Aryl Porphyrins and Application for Supporting Ir(III)‐Catalyzed Enantioselective C−H Alkylation

A hitherto unknown class of C4-symmetric Caryl Cβ (C3, C8, C13, C18) axially chiral porphyrins has been synthesized and the application of their iridium (Ir) complexes in catalytic asymmetric C(sp3) H functionalization is documented. Cyclotetramerization o ...

Catalytic Enantioselective Synthesis of Inherently Chiral Macrocycles by Dynamic Kinetic Resolution

Jieping Zhu, Shuo Tong

Kinetically fast racemization of chiral substrates through an achiral intermediate and enantioselective functionalization of one of the enantiomeric substrates forms the basis of the dynamic kinetic resolution (DKR) of centrally chiral molecules. We report ...

Influence of the hydrophile-lipophile balance of perfluorinated surfactants on the emulsion stability

Esther Amstad, Gaia De Angelis

Emulsions are omnipresent in our everyday life; for example, in food, certain drug and cosmetic formulations, agriculture, and as paints. Moreover, they are frequently used to perform high-throughput screening assays with minimum sample volumes. Key to the ...
