Preparation and Spectral Properties of Substituted Heterocyclobutan-3-Ones [PDF]
, 1981 In the past decade some new interpretations of orbital interactions in small rings have resulted from the observations of valence shell ionization potentials. These ionization potentials were obtained from a technique known as photoelectron spectroscopy,

Design of peptide-containing N5-unmodified neutral flavins that catalyze aerobic oxygenations [PDF]
, 2020 Simulation of the monooxygenation function of flavoenzyme (Fl-Enz) has been long-studied with N5-modified cationic flavins (FlEt+), but never with N5-unmodified neutral flavins (Fl) despite the fact that Fl is genuinely equal to the active center of Fl ...

Food Science &Nutrition, Volume 14, Issue 4, April 2026.Flat peach juice was subjected to thermal sterilization (high‐temperature sterilization and pasteurization) and nonthermal sterilization (high hydrostatic pressure and microwave sterilization). Volatile profiles and sensory attributes were characterized using HS–GC–IMS, HS–SPME–GC–MS, and bionic sensory evaluation.

The cycloaddition of ketenes and silyl enol ethers [PDF]
, 1979 The (2+2) cycloaddition of ketenes and trimethylsilyl enol ethers was found to proceed in good yield to give trimethylsiloxycyclobutanones of unique and interesting regiochemistry and stereochemistry.

ChemBioChem, Volume 27, Issue 6, 27 March 2026.The application of biocatalytic cascades for organic synthesis can be encouraged through the use of easy‐to‐handle, immobilised enzymes and common laboratory equipment. We present a sequential biocatalytic cascade reaction that couples a transaminase (ATA) with a lipase, and achieves high conversion and enantioselectivity through by‐product removal ...

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.Diese Studie untersucht den Einfluss von Spuren diverser Elemente des p‐Blocks in der elektrochemischen reduktiven Aminierung, wobei sich für Pb mit Bi eine weniger toxische Alternative gezeigt hat. Die Verwendung von Bi als Additiv wurde weiter optimiert, indem der Einfluss der Additivkonzentration, der Reaktionstemperatur und des Kathodenmaterials ...
