Chelate-modified polymers for atmospheric gas chromatography [PDF]

, 1980
Chromatographic materials were developed to serve as the stationary phase of columns used in the separation of atmospheric gases. These materials consist of a crosslinked porous polymer matrix, e.g., a divinylbenzene polymer, into which has been embedded

Characterization of the pattern of development of key compounds contributing to aroma quality of chicken meat and their metabolic markers

Animal Research and One Health, EarlyView.
The graphical abstract shows the principal results of this study. Eight major aroma‐contributing compounds (nonanal, octanal, dimethyl tetrasulfide, hexanal, 1‐octen‐3‐ol, (E)‐2‐nonenal, heptanal, and (E,E)‐2,4‐decadienal) were identified by electronic nose and GC‐O‐MS analysis, and their content increased with age.

Postsynthetic Modifications of Amide‐Enaminone‐Based [2]Rotaxanes for the Stereocontrolled Synthesis of Functionalized β‐Lactams

ChemistryEurope, EarlyView.
Novel amido‐enaminone threads efficiently template the formation of hydrogen‐bonded [2]rotaxanes and enable diverse postsynthetic modifications. Benzyl groups promote diastereoselective cyclizations to interlocked lactams while the enaminone motif allows stopper exchange while preserving the mechanical bond.
