  • Patent number: 11884639
    Abstract: A field of asymmetric catalytic synthesis, and in particular a preparation method for a high optical indoxacarb intermediate includes reacting 5-chloro-2-methoxycarbonyl-1-indanone ester (or indanone ester for short) with an oxidizing agent in the presence of a chiral Zr-salen polymer to obtain an indoxacarb intermediate (2S)-5-chloro-2,3-dihydro-2-hydroxy-1-oxo-1H-indole-2-carboxylic acid methyl ester. The yield is stabilized between 86% and 90%, and the S-enantiomer content is up to 99%. Such catalyst can replace catalysts such as cinchonine, and greatly increase the content of the effective S-enantiomer of the indoxacarb, so that the content of the hydroxyl intermediate S-enantiomer of the indoxacarb is raised from 75% to 99% or more. In addition, the chiral Zr-salen polymer catalyst is recycled without retreatment, and can be recycled at least 5 times or more, greatly reducing the production cost and laying a foundation for the industrial production of high quality indoxacarb.

    Abstract: A catalyst and a method for preparing S-indoxacarb using the catalyst. The catalyst is prepared using 3-tert-butyl-5-(chloromethyl)salicylaldehyde and cyclohexanediamine as raw materials, where an original quinine catalyst such as cinchonine is replaced with the catalyst for application in the asymmetric synthesis of tert-butyl hydroperoxide and 5-chloro-2-methoxycarbonyl-1-indanone ester, greatly improving selection in the asymmetric synthesis process, with the S-enantiomer content increasing from 75% to over 98%, achieving the recycling of a high-efficiency chiral catalyst, and greatly reducing production costs. The synthesis process of the catalyst is simple and is favorable for industrialization, and lays good foundations for the production of high-quality indoxacarb.

  • Patent number: 11218523
    Abstract: To enable fast startup of an audio/video receiver device and quick receipt of a first audio/video stream, is provided a method in an intermediate device in between a router device and the receiver device. The intermediate device snoops the communication between the audio/video receiver device and the router device to determine the protocol version of the router device to subscribe to a transmission of an audio/video stream and to determine that the receiver device is starting up. If the protocol version is a version not supporting Source Specific Multicast and the receiver device is booting, a message indicating the protocol version is transmitted to the receiver device during starting up of the receiver device so that the latter can switch to a protocol version supported by the IP multicast router device without further delay.
