1Ring opening [3+2] cyclization of azaoxyallyl cations with benzo[d]-isoxazoles:Efficient access to 2-hydroxyaryl-oxazolines显示文摘A selective ring-opening [3+2] cyclization reaction of benzo[d]isoxazoles with 2-bromo-propanamides has been developed.The azaoxyallyl cation intermediates are employed as C^O 3-atom synthon to build oxa-heterocycles via the selectivity of suitable cyclization partners.This transformation provides rapid access to highly functionalized 2-hydroxyaryl-oxazolines under mild conditions and excellent regioselectivity.Yicheng He Chao Pi Yangjie Wu Xiuling Cui 2020Chinese Chemical Letters2020,31,2:0
2Design Method of Reversely Switched Dynistor Based Pulse Circuit Without Magnetic Switch显示文摘In the reversely switched dynistor(RSD)-based pulse power circuits,a magnetic switch is usually necessary to be applied together with a main switch.It occupies space and needs a magnetic reset.In this paper,a method of designing a RSD-based pulse circuit without a magnetic switch is proposed.In the pulse circuit,a RBDT(reverse blocking diode thyristor)is used to separate the two capacitors and provide an energy branch.The pre-charge time of the RSD can be guaranteed by the energy conversion between the capacitors and inductors,instead of the saturation of the magnetic switch.In addition,the energy which is reused to trigger the RSD is based on an inductor.The pulse circuit is evaluated by simulations and practical experiments.According to the experimental results,the factors affecting the load pulse current and triggering of the RSD and RBDT are studied.Meanwhile,a method to reduce the current in the trigger switch,which is a potential problem in the pulse circuit,is proposed.Yicheng Pi Lin Liang Xiaoxue Yan 2023CSEE Journal of Power and Energy Systems2023,9,1:0
