Dynamic Transformation between Covalent Organic Frameworks and Discrete Organic Cages

   From The Journal: JACS   Abstract We propose a dynamic covalent chemistry (DCC)-induced linker exchange strategy for the structural transformation between covalent organic frameworks (COFs) and cages for the first time. Studies have shown that the COF-to-cage and cage-to-COF transformations were realized by using borate bonds and imine bonds, respectively, as linkages. Self-sorting experiments suggested that borate cages and imine COFs are thermodynamic minimum compounds. This research builds a bridge between discrete and polymeric organic scaffolds ...

Precise 1H- and 13C-NMR reassignment of dehydrocrebanine by 10-mg INADEQUATE and in silico analysis: With an alert for its toxicity

   From the journal: Tetrahedron   Abstract During our continuous investigation on a Thai traditional medicinal plant, Stephania venosa Spreng, an alkaloid that seemed to be O-methyldehydrobulbocapnine (MDB) or dehydrocrebanine (DC), had been isolated. However, none of the previously reported 1H- and 13C-NMR data for MDB and DC matched our charts. Thus, we herein report the unambiguous determination of the alkaloid structure as DC via a successful INADEQUATE experiment using 10 mg of the unenriched natural specimen as well as an in silico estimation. Furthermore, ...

13C–13C spin-coupling constants in crystalline 13C-labeled saccharides: conformational effects interrogated by solid-state 13C NMR spectroscopy

   From the journal: Physical Chemistry Chemical Physics   Abstract Solid-state 13C NMR spectroscopy has been used in conjunction with selectively 13C-labeled mono- and disaccharides to measure 13C–13C spin-couplings (JCC) in crystalline samples. This experimental approach allows direct correlation of JCC values with specific molecular conformations since, in crystalline samples, molecular conformation is essentially static and can be determined by X-ray crystallography. JCC values measured in the solid-state in known molecular conformations can then be compared to corresponding JCC values calculated in the same conformations using ...

JEOL NMR Article On Cover Of Solid State Nuclear Magnetic Resonance

A joint paper was published with the RIKEN-JEOL Collaboration Center, Institute for Integrated Cell-Material Sciences (WPI-iCeMS), University of Warwick, and JEOL RESONANCE Inc. This article has also been featured on the cover! Highlights: Selective detection of 1H signals of API in a tablet formulation is proposed. 1H signals of excipients are suppressed. 1H signals in the vicinity of nuclei (here 14N) which only appear in API are excited. 1H{14N} magnetization is diffused to 1Hs in API crystals by RFDR recoupling.   Link to the ...
