In this paper, the issue of adaptive event-triggered output-feedback control for a class of switched nonlinear systems with time-varying delays is investigated. By adopting the mode-dependent average dwell time (MDADT) method and the backstepping technique, an adaptive neural output-feedback control strategy is proposed for the switched system with event-triggered mechanism. In the process of controller design, an intelligent approximation technique and a switched filter are introduced to overcome the difficulties caused by the unknown nonlinear functions and the immeasurable states, respectively. Moreover, the appropriate Lyapunov-Krasovskii functionals are designed to compensate the effects of time delays. It is proved that the proposed control strategy guarantees that all the signals in the switched closed-loop systems are bounded under arbitrary switchings with MDADT. In the end, two simulation examples are provided to illustrate the feasibility of the developed control strategy.

A novel strategy for asymmetric Shono‐type oxidative cross‐coupling has been developed by merging copper catalysis and electrochemistry, affording C1‐alkynylated tetrahydroisoquinolines with good to excellent enantioselectivity. The use of TEMPO as a co‐catalytic redox mediator is crucial not only for oxidizing a tetrahydroisoquinoline to an iminium ion species but also for decreasing the oxidation potential of the reaction. A novel bisoxazoline ligand is also reported.

The scalable and efficient method provides various polycyclic spirooxindoles with three contiguous chiral centers, two of which are quarternary, in excellent yields and with high to excellent dia‐ and enantioselectivities.
