Configuration-Dependent Medium-Sized Ring Formation: Chiral Molecular Framework with Three-Dimensional Architecture [PDF]
, 2020 This report describes a configuration-dependent [6 + 8 + 5] fused ring formation via a tandem cyclic N-acyliminium nucleophilic addition reaction. Cyclization of the acyclic precursor prepared on a solid phase using l-Ser and a racemic mixture of Fmoc ...

Indandiazocines: Unidirectional molecular switches
ScienceOpen Research, 2015 We report theoretical investigations on azobenzene-based indandiazocines, novel chiral systems that perform unidirectional cis↔trans isomerizations upon photo-excitation. For three different systems of this kind, we have simulated excited-state surface-

Synthesis of mono-functionalized S-diazocines via intramolecular Baeyer–Mills reactions
Beilstein Journal of Organic Chemistry, 2018 Herein we report a reliable method to synthesize mono-functionalized S-diazocines in reproducible yields via intramolecular Baeyer–Mills reactions. Diazocines exhibit excellent photoswitchable properties. As opposed to azobenzenes they are more stable in

Synergistic Two‐Color Photochemical Polymer Network Formation and Lithography
Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.Two photoswitches, able to respond to disparate wavelengths, are integrated into multi‐functional polymer architectures to form a photoresist that responds to curing upon irradiation with two distinct monochromatic colors of light, enabling two‐color lithography.
