Abstract The efficiency of artificial neural networks (ANNs) for modeling the electrical impedance spectroscopy of (4E)-2-amino-3-cyanobenzo[b]oxocin-6-one was investigated. The experimental data for electrical impedance and dissipation factor were used as input data for the model.

New Journal of Chemistry, 2017
Palladium-catalyzed dual strategies of cascade cyclocarbopalladation/cross-coupling of alkynes and a reductive Heck reaction have been developed to construct dibenzo[c,f]oxocine frameworks with tri- and tetra-substituted exo-cyclic alkenes with high stereo- and regio-control.

Organic Letters
Herein, we present a visible-light-induced protocol for the synthesis of highly functionalized oxo-bridged oxocine skeletons. This method generates carbenes via visible-light-induced ortho-acyl diazo compounds, which are rapidly intercepted by the oxygen atom of an intermolecular acyl group to form a cyclic 1,3-dipole.
