Controlled Helix‐Sense‐Selective Polymerization of 4‐Alkoxy‐3,5‐Bis(hydroxymethyl)phenylacetylene Derivative Initiated by Chiral Hexa‐1,3,5‐Trienylrhodium(I) Complex

ChemistryEurope, EarlyView.
The controlled helix‐sense‐selective polymerization of an achiral 4‐alkoxy‐3,5‐bis(hydroxymethyl)phenylacetylene derivative using an axially chiral heptaarylhexa‐1,3,5‐trienylrhodium(I) complex bearing a hydrophobic tert‐butyl group and a tetrafluorobenzobarrelene ligand as the initiator is achieved, thereby elucidating the relationship between ...

Quantum Chemistry Investigation of Linear and Nonlinear (chir)optical Properties of Oligoamide Foldamers

ChemistryEurope, EarlyView.
The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Enantioselective Synthesis of Sulfinamidines via Asymmetric Rhodium–Catalyzed Imidation of Sulfenamides

ChemistryEurope, EarlyView.
In this work, a catalytic enantioselective imidation approach is presented for the preparation of enantioenriched sulfinamidines from sulfenamides, employing a chiral dirhodium(II) tetracarboxylate catalyst. This method enables the imidation of N,N‐bisalkyl sulfenamides in yields of up to 98% and enantiomeric ratios up to 98:2, with a catalyst loading ...

Association Between D‐amino Acids in Natto (fermented soybeans) and Kidney Dysfunction

ChemFoodChem, EarlyView.
XX XX ABSTRACT In this study, we examined clinical and cohort data to explore the potential renoprotective effects of natto (fermented soybeans) consumption and its relationship with D‐amino acids. In a clinical study, ten healthy adults consumed one 40‐g pack of natto three times in a single day, and plasma and urine samples were collected 1 h and 24 ...
