  • Publication number: 20210276947
    Abstract: The disclosure provides processes for preparing 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile and for preparing sulindac, relating to the field of medicine. The former comprises mixing 6-fluoro-2-methyl-1-indanone, cyanoacetic acid, a first organic solvent and an acetic acid-based catalyst to proceed with a first condensation reaction to give a first condensation reaction solution, which contains 5-fluoro-2-methyl-3-indanacetonitrile; and mixing the first condensation reaction solution, per se, with a base, a second organic solvent and 4-(methylthio)benzaldehyde to proceed with a second condensation reaction to give 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile. The process is a one-pot process without separation of 5-fluoro-2-methyl-3-indanacetonitrile from the solvent, shortening the synthetic route, simplifying the preparation process and improving the 5-fluoro-2-methyl-1-(4-methylthiobenzylidene)-3-indanacetonitrile yield.

  • Patent number: 11115379
    Abstract: Described herein are systems and methods to manage Internet Protocol (IP) address discovery in a software defined networking (SDN) environment. In one example, a manager may generate an IP address discovery configuration and pass the IP address discovery configuration to a controller. Once received, the controller may obtain a discovered list from a hypervisor of one or more IP addresses associated with one or more logical ports and update a realized list for the one or more logical ports based on the discovered list and the IP address discovery configuration.

  • Publication number: 20200280537
    Abstract: Described herein are systems and methods to manage blacklists and duplicate addresses in software defined networks (SDNs). In one implementation, a method includes, in a control plane and data plane of an SDN environment, obtaining a blacklist for a logical port in the SDN environment. The method further includes deleting realized address bindings in a realized address list for the logical port that match the one or more address bindings in the blacklist and preventing subsequent address bindings that match the one or more address bindings in the blacklist from being added to the realized address list.

  • Patent number: 10604466
    Abstract: The present invention provides a method for preparing a resveratrol compound, and belongs to the technical field of organic synthesis. In the present invention, first alkoxy-substituted benzyl halide, alkoxy-substituted benzaldehyde and a metal catalyst are subjected to oxidative addition and reduction elimination reactions to obtain alkoxy-substituted diphenylethanone; and then the alkoxy-substituted diphenylethanone and a metal catalyst are subjected to reduction, trans elimination and selective debenzylation reactions under a hydrogen atmosphere to obtain the resveratrol compound. In the preparation method of the present invention, the hydrogenation reduction, trans elimination and selective debenzylation reactions can be achieved just by a one-pot process, where the reaction directly obtains a trans olefin, thereby avoiding the formation of a isomer; and also the reaction selectively catalyzes debenzylation to eliminate Lewis acids from the source, and has the advantage of a high yield.
